Peter Barlow 1811, on M Mersenne numbers have a particulary simple test for primality, the Lucas-Lehmer test The number-theoretic interest in Mersenne primes comes from the following theorem: if m and n are natural numbers, with n greater than 1, and if m n -1 is prime, then m is 2 and n is prime.

Mersenne prime From Wikipedia, the free encyclopedia. In mathematics , a Mersenne prime is a prime number that is one less than a power of two More generally, Mersenne numbers (not necessarily primes, but candidates for primes) are numbers that are one less than a prime power of two; hence, M n n Mersenne primes have a close connection to perfect numbers , which are numbers that are equal to the sum of their proper divisors. Historically, the study of Mersenne primes was motivated by this connection; in the 4th century BC Euclid demonstrated that if M is a Mersenne prime then M(M+1)/2 is a perfect number. Two millennia later, in the 18th century Euler proved that all even perfect numbers have this form. No odd perfect numbers are known, and it is suspected that none exist. It is currently unknown whether there is an infinite number of Mersenne primes. The calculation shows that M n can be prime only if n itself is prime, which simplifies the search for Mersenne primes considerably. But the converse is not true; M n may be composite even though n is prime. For example, 2

Great Internet Mersenne Prime Search From Wikipedia, the free encyclopedia. The Great Internet Mersenne Prime Search , or GIMPS , is a collaborative project of volunteers, who use Prime 95 and MPrime , special open source software that can be downloaded from the Internet for free, in order to search for Mersenne prime numbers . The project was founded and the prime testing software was written by George Woltman Scott Kurowski wrote the PrimeNet server that supports the research to demonstrate Entropia distributed computing software, a company he founded in 1997. This project has been rather successful, although seemingly useless: it has found a total of 7 Mersenne primes , each of which was the largest known prime at the time of discovery. The largest known prime as of May , is 2 Josh Findley . Refer to the article on Mersenne primes numbers for the complete list of GIMPS successes As of March , GIMPS has a sustained throughput of approximately 14 teraflops Technically the GIMPS software is not open source , since it has a restriction which most open source/ free software EFF prizes are claimed.

Great Internet Mersenne Prime Search and I found it !! Links Go Key Resource Number Theory Topic 36th Mersenne Prime Found On Sunday 24 th August 1997 I found the 36 th Mersenne Prime at the time it was the world's largest known prime number. It took my Pentium 100 PC fifteen days to prove the number prime. David Slowinski has verified the result on a Cray T90 Supercomputer. This new number is digits in length. George Woltman's announcement Chris Caldwell's announcement Read about it in Science News Article in the London Times ... CNN Article How big is that ? It would fill a 450 page paperback book If written out it would stretch for 1.4 miles or 2.2 Km It would take 28 days to say the number, speaking for 8 hours a day Please note though that I was just the lucky one of over 4500 volunteers all searching for these gigantic numbers, why not join us...... .....GIMPS Stands for the Great Internet Mersenne Prime Search, and is a world wide project involving over 4500 participants (@ September 1998), coordinated by George Woltman who maintains the GIMPS site and Scott Kurowski who runs the Primenet Internet Server . Every member of the group runs some Free Software Please note that this size of task would have previously only been possible on large Supercomputers such as the Cray that was used to verify this result, but by running the software on thousands of individual machines we can collectively surpass the power of even the most powerful supercomputer.

General Computing Terms Mersenne prime A Mersenne (also spelled Marsenne) prime is a specific type of prime number . It must be reducible to the form 2 n - 1, where n is a prime number. The term comes from the surname of a French monk who first defined it. The first few known values of n that produce Mersenne primes are where n n n n n n n n n = 61, and n With the advent of computers to perform number-crunching tasks formerly done by humans, ever-larger Mersenne primes (and primes in general) have been found. The quest to find prime numbers is akin to other numerical searches done by computers. Examples are the decimal expansions of irrational number s such as pi (the circumference-to-diameter ratio of a circle) or e (the natural logarithm base). But the 'next' (unknown today, known tomorrow) prime is more difficult to find than the 'next' digit in the expansion of an irrational number. It takes the most powerful computer a long time to check a large number to determine if it is prime, and an even longer time to determine if it is a Mersenne prime. For this reason, Mersenne primes are of particular interest to developers of strong encryption methods.

In the formalist view, it is the investigation of axiomatically defined abstract structures using logic and mathematical notation; other views are described in Philosophy of mathematics.
