Extractions: GIMPS , founded by George Woltman in January of 1996, is dedicated to the rigorous search for new Mersenne primes. A Mersenne number is any number of the form 2 p - 1 where p is a prime. A Mersenne prime is a Mersenne number which is prime. Gimps connects the pure research of finding new Mersenne primes with the technology of the computer. The goal of GIMPS is to test the primality of every Mersenne number with an exponent less than 20,500,000. GIMPS uses a program written by Woltman that implements the Lucas-Lehmer Test and multiplies using Fast Fourier Transforms along with network software and the PrimeNet server developed by Scott Kurowski and the company Entropia . Over 12,000 number theory enthusiasts have harnessed thousands of small computers to search for these huge prime numbers using Woltman's program. GIMPS has now found the four largest known Mersenne primes. The following list gives these four Mersenne primes, their discoverer, and the date of their discovery.

Extractions: Mersenne Primes Biologically, every male as an infant foetus initially enjoys a feminine identity. What may not be quite so obvious is that this parallels the very nature of the prime number system, which starts with an even (feminine) number. Indeed, this would suggest that every prime number can ultimately be derived from 2. A famous example of this approach is the set of Mersenne primes. (Another is the set of Fermat primes). Now Mersenne primes are especially interesting in that they also generate another fascinating class of numbers - with considerable psycho-mathematical significance i.e. perfect numbers. A Mersenne prime is always of the form 2 n - 1 (n is a positive integer). For example, - 1 = 31 is a Mersenne prime. Now, there are two points which I wish to point out which illustrate the transrational approach. 1) The power of 2 (i.e. the qualitative vertical number) must itself be prime, if the resulting number (i.e. the reduced quantitative horizontal number) is to be prime. In our example, the qualitative number 5 is prime, and the (reduced) quantitative number 31 is prime. 2) The resulting prime number is closely associated with a highly composite number.

Extractions: Mersenne Primes Mersenne Primes: A prime of the form 2 p - 1, where p is a prime. The number of known primes of this form is over 30, and keeps increasing as they are discovered by using computers. In 1995, the largest known was 2 - 1. Each Mersenne prime gives rise to an even perfect number Marin Mersenne Died: 1648 Martin Mersenne was a french monk, philosopher and mathematician who provided a valuable channel of communication between such contempories as Descartes, Fermat, Galileo and Pascal: 'To inform Mersenne of a discovery is to publish it throughout the whole of Europe.' In an attempt to find a formula for prime numbers, he considered the numbers 2 p - 1, where p is a prime.

Extractions: NUMBERS AND COMPUTERS (9) by Albert N. Debono MERSENNE PRIMES Since we are discussing primes again perhaps we should repeat the definition of a prime number. A prime is a whole number greater than 1, whose only exact divisors are 1 and the number itself. Thus 2, 3, 5, 7, 11, 13 are primes whereas 4, 6, 8, 9, 10, 12, 14, 15 are not. Refer to Numbers and Computers (4) for hints on how to write a computer program to find them. The number of primes is infinite and 2 is the only even prime.

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;

If a Mersenne number turns out to be a prime number, then it is calleda mersenne prime. (c) Do you think M 21 is a mersenne prime?
http://home1.pacific.net.sg/~novelway/MEW2/lesson2.html

Extractions: How are Mersenne primes related to perfect numbers? If a Mersenne number turns out to be a prime number, then it is called a Mersenne prime You have computed the first 5 Mersenne primes: 3, 7, 31, 127, 8191. Each of these numbers in turn gives a perfect number when multiplied by its previous power of 2. (b) Two perfect numbers were discovered in 1588, both by Cataldi. These two perfect numbers can be obtained from the Mersenne primes M - 1 and M - 1. Can you compute these two perfect numbers with the help of your calculator? (c) Do you think M is a Mersenne prime? By now, you should have realised why numbers of the form 2 n - 1 have so much appeal. Whenever a prime number of this form is found, a perfect number is immediately obtained, as was proven by Euclid.
