search. In mathematics, a Mersenne prime is a prime that is one less than a power of two. For example, 3 = 4 − 1 = 2 2 − 1 is a Mersenne prime; so is 7 = 8 − 1 = 2 3 − 1. On the other hand, 15 = 16 − 1 = 2 4 − 1, for example, is not a prime, because 15 is divisible by 3 and 5.
Since 1996, the Great Internet Mersenne Prime Search 16 Apr 2018 A Mersenne prime is of the form 2n-1 (n is an integer). For example, if n = 3, then 23-1 gives us the prime number 7. Of course Mersenne primes were first studied because of the remarkable properties that every Mersenne prime corresponds to exactly one perfect number. L. Welsh Mersenne primes (or Mersenne numbers) are connected to prime numbers.

12 -- Mathematicians at the Great Internet Mersenne Prime Search (GIMPS) came across the bug while running Prime95 - an application used to calculate prime numbers - in their search to find Mersenne Prime … Prime Factorization for small numbers; Calculate number of digits in an exponent; Convert GIMPS Factoring Effort to PFactor; External Links: Mersenne Forum; Prime Wiki; GPU to 72 by Chris Halsall; GIMPS Status; Factorization using ECM; Mersenne software download mirror; Calculate bit size of factor: How far with Prime95 trial-factor an exponent Mersenne Prime is a prime number o f the same format that is (2^n)-1 for some integer n (not all). Mersenne primes help in generating large prime numbers which are very helpful while encryption Often a prime just less than a power of 2 is used (the Mersenne primes 231−1 and 261−1 are popular), so that the reduction modulo m = 2e − d can be computed as (ax mod 2e) + d. Linear congruential generator-Wikipedia. All larger known primes are Mersenne primes, discovered by GIMPS. the last Mersenne prime shown above was the largest known prime.
For m to be prime, p itself must be prime, but that is not sufficient.

A Mersenne prime is a Mersenne number that is a prime number. This however, is not sufficient. Many mathematicians prefer the definition of a Mersenne number where exponent n has to be a prime number. Mersenne Primes: Wallpaper: Foundation: Diet: About.
