Extractions: December 5, 2001Today, the number 2 - 1 was announced to be a Mersenne prime, making it the largest such number to be discovered to date. This news followed a November 14 report to the mailing list of the GIMPS project that a new unspecified Mersenne number had passed the Lucas-Lehmer test , identifying it as a prime number. Mersenne numbers are numbers of the form M n n - 1. For example, M - 1 = 127 is a Mersenne number. The study of such numbers has a long and interesting history, and the search for Mersenne numbers that are prime (so-called Mersenne primes ) has been a computationally challenging exercise requiring the world's fastest computers. The complete list of indices n for previously known Mersenne primes is given by n = 2, 3, 5, 7, 13, 17, 19, 31, 61, 89, 107, 127, 521, 607, 1279, 2203, 2281, 3217, 4253, 4423, 9689, 9941, 11213, 19937, 21701, 23209, 44497, 86243, 110503, 132049, 216091, 756839, 859433, 1257787, 1398269, 2976221, 3021377, and 6972593 (Sloane's ). The last of these has a whopping 2,098,960 digits. However, the region between the last two previously known Mersenne primes has not been completely searched, so it is not known if

If you don't want a lot of e-mail DON'T click here. Yes. I'm a member of that, too. From one year to the next, the largest prime number is usually a Mersenne prime, because they are much easier to check. Mersenne primes, and Mersenne numbers in general, were discovered by the French monk Marin Mersenne, who is depicted in the picture above. There are two main ways to find these numbers: one is to use a supercomputer, such as a Cray T3E. The other way is get a lot of personal computers together. This is what George Woltman did. There are now over 6000 participants in George's Mersenne club. David Slowinsky might never find another Mersenne prime. George's club has found the last four: , and and has also completed various other search goals, such as proving that M32, 33, 34, and 35 are the numbers we originally expected that they were, by testing all the ones in between.

Mersenne Prime Numbers The concept of a mersenne prime is evolved from that of a perfect number. Letp be a prime and Mp = 2p 1 the pth Mersenne number. http://www.resort.com/~banshee/Info/mersenne.html
Extractions: Marin Mersenne (1588-1648) was a Franciscan friar who lived most of his life in Parisian cloisters. He was the author of Cognitata Physico-Mathematica which stated without proof that M p is prime for p = 2, 3, 5, 7, 13, 17, 19, 31, 67, 127, and 257 and for no other primes p for p p , Mersenne contributed to the development of number theory through his extensive correspondence with many mathematicians, including Fermat. Mersenne effectively served as a clearing house and a disseminator of new mathematical ideas in the 17th century. Kenneth Rosen, Elementary Number Theory; Addison Wesley The concept of a Mersenne Prime is evolved from that of a perfect number . A perfect number is an integer for which the sum of its divisors is twice the number. For example: (6) = 1 + 2 + 3 + 6 = 12 = 2*6 thus 6 is a perfect number.

A Mersenne prime is a prime number that is one less than a power of two. For example, 3 = 4-1 = 2 -1 is a Mersenne prime. So is 7 = 8-1 = 2 -1. But 15 = 16-1 = 2 -1 is not a prime. Fast algorithms for finding Mersenne primes are available, and this is why the largest known prime numbers today are Mersenne primes. Mersenne primes have a deep 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

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
