Chinese remainder theorem (algorithm) Definition: An integer n can be solved uniquely mod LCM(A(i)) Note: For example, knowing the remainder of n when it's divided by 3 and the remainder when it's divided by 5 allows you to determine the remainder of n when it's divided by LCM(3,5) = 15.

Chinese Remainder Theorem Theorem : Suppose that m , m , ..., m r are pairwise relatively prime positive integers, and let a , a , ..., a r be integers. Then the system of congruences, x = a i (mod m i x m x ... x m r , which is given by: x = a M y + a M y + ... + a r M r y r (mod M), where M i = M/m i and y i = (M i (mod m i Pf : Notice that gcd(M i , m i i all exist (and can be determined easily from the extended Euclidean Algorithm). Now, notice that since M i y i = 1 (mod m i ), we have a i M i y i = a i (mod m i i M i y i = (mod m j ) if j is not i (since m j i in this case). Thus, we see that x = a i (mod m i If there were two solutions, say x , and x , then we would have x - x = (mod m i ) for all i, so x - x = (mod M), i.e., they are the same modulo M. Example Find the smallest multiple of 10 which has remainder 2 when divided by 3, and remainder 3 when divided by 7. We are looking for a number which satisfies the congruences, x = 2 mod 3, x = 3 mod 7, x = mod 2 and x = mod 5. Since, 2, 3, 5 and 7 are all relatively prime in pairs, the Chinese Remainder Theorem tells us that there is a unique solution modulo 210 ( = 2x3x5x7). We calculate the M i 's and y i 's as follows: M = 210/2 = 105; y

: Number Theory 101 (Chinese Remainder Theorem) I said, in the last lesson, that we would get into factoring during this lesson. I had forgotten, at the time, that I wanted to hit on the Chinese Remainder Theorem. So, factoring will have to wait until next class. In other news, I entirely blew creating a class for two weeks ago. And, last week, I was sick to the point of inertness for 80% of the week. My apologies for blowing the class two weeks ago. I hope the content is interesting enough to bring y'all back after this unscheduled hiatus. Greatest Common Divisor (Continued) One more interesting thing to note about the Greatest Common Divisor of two numbers (at least one of which is non-zero). The Greatest Common Divisor of two numbers is the smallest positive number which can be written as a linear combination of the two numbers. It shouldn't come as a surprise to you that the proof of this takes advantage of the Well-Ordering Principle. Just about any mathematical statement containing "smallest number" requires the Well-Ordering Principle. The proof creates a set of all positive numbers a * u + b * v where u and v are integers. It shows that the set is non-empty (one way to do this is to let

Recommend this site Subject: Re: Chinese remainder theorem Date: Tue, 2 Sep 1997 00:00:59 -0400 From: Alex Bogomolny Dear Tan: Yours is an example of problems solved in general case by what's known as the Chinese Remainder Theorem. You can look it up in O.Ore, "Number Theory and Its History", or H.Davenport, "The Higher Arithmetic" Both available through my bookstore. In your particular case, you are looking for a number X such that X = 1 (mod 2,3,4) and X = (mod 5) which means that divided by 2,3,4 X has the remainder 1 while divided by 5 the remainder is 0. The first three condition say that (X - 1) is divided by 2,3 and 4, i.e., by their least common multiple which is 12. Therefore, X - 1 = 12t for some integer t. From X = (mod 5) it follows that X - 1 = 4 (mod 5). Or 12t = 4(mod 5), 3t = 1 (mod 5). As you can check then, t = 5k + 2 for an integer k. Combining this with X = 12t + 1 we get X = 60k + 25. There are three numbers below 200 in this form: 25, 85 and 145. Best regards

Chinese Remainder Problem - The Beginning. What is it? These particular kinds of mathematical problem falls in the category of indeterminate analysis. Usually, it appears in the form as such (in modern notation): N = m1x + r1 N = m2y + r2 N = m3z + r3 Or in modern number theory notation: N r1 (mod m1) N r2 (mod m2) N r3 (mod m3) Aside: Writing N r1 (mod m1) [this means N is congruent to r1 modulo m1] means that N divided by m1 leaves r1 as the remainder. The goal here is to find the smallest positive integer satisfying the congruences states above. Origins. Now that you know what a Chinese Remainder Problem is, you must be wondering why or what has this particular kind of problem to do with Chinese Mathematical History. The reason why it is called the Chinese Remainder Problem is because the earliest versions of these congruence problems occured in early Chinese mathematical works. The earliest of such works that contains the Chinese Remainder Problem is the Sun Tzu Suan Ching (also known as Sunzi suanjing) written in approximately late third century by Sun Zi . Problem 26 (also known as the problem of Master Sun) in the third volume of the Sun Tzu Suan Ching offers the earliest recorded Chinese Remainder Problem. Problem 26 is as stated below: "We have a number of things, but we do not know exactly how many. If we count them by threes we have two left over. If we count them by fives we have three left over. If we count them by sevens we have two left over. How many things are there?" (Quoted from Sun Tze Suan Ching).

Join Our Mailing List CHINESE REMAINDER THEOREM Applications in Computing, Coding, Cryptography by C Ding (Turku Centre for Computer Science, Finland) , D Pei (Chinese Academy of Science, Beijing) (University of Turku, Finland) Chinese Remainder Theorem , CRT, is one of the jewels of mathematics. It is a perfect combination of beauty and utility or, in the words of Horace, omne tulit punctum qui miscuit utile dulci. Known already for ages, CRT continues to present itself in new contexts and open vistas for new types of applications. So far, its usefulness has been obvious within the realm of "three C's". Computing was its original field of application, and continues to be important as regards various aspects of algorithmics and modular computations. Theory of codes and cryptography are two more recent fields of application. This book tells about CRT, its background and philosophy, history, generalizations and, most importantly, its applications. The book is self-contained. This means that no factual knowledge is assumed on the part of the reader. We even provide brief tutorials on relevant subjects, algebra and information theory. However, some mathematical maturity is surely a prerequisite, as our presentation is at an advanced undergraduate or beginning graduate level. We have tried to make the exposition innovative, many of the individual results being new. We will return to this matter, as well as to the interdependence of the various parts of the book, at the end of the Introduction.

The Chinese Remainder Theorem Last updated: August 7th, 1995 The Chinese Remainder Theorem (CRT) gives the answer to the problem: Find the number x, that satisfies all the n equations simultaneously: x = r1 (mod p1) x = r2 (mod p2) x = rk (mod pk) x = rn (mod pn) We will assume here (for practical purposes) that the moduli pk are primes. Then there exists a unique solution x modulo p1*p2*...*pn. The solution can be found with the following algorithm: Let P=p1*p2*...*pn Let the numbers T1...Tn be defined so that for each Tk (k=1...n) (P/pk)*Tk=1 (mod pk) that is, Tk is the inverse of P/pk (mod pk). The inverse of a (mod p) can be found for example by calculating a^(p-2) (mod p). Note that a*a^(p-2)=a^(p-1)=1 (mod p). Then the solution is x = (P/p1)*r1*T1 + (P/p2)*r2*T2 + ... + (P/pn)*rn*Tn (mod P) The good thing is, that you can calculate the factors (P/pk)*Tk beforehand, and then to get x for different rk, you only need to do simple multiplications and additions (supposing that the primes pk remain the same). When using the CRT in a number theoretic transform, the algorithm can be implemented very efficiently using only single-precision arithmetic when rk
