Definition of Mersenne number in English: Mersenne numbernounməːˈsɛnmərˈsen ˌnəmbər Mathematics A number of the form 2p−1, where p is a prime number. Such a number which is itself prime is also called a Mersenne prime. Example sentencesExamples - Primes of the form 2 n - 1 are known as Mersenne primes, and these numbers figure prominently in the search for the largest known prime.
- And the Great Internet Mersenne Prime Search continues to unearth new Mersenne primes.
- Written in the form 2 p - 1, where the exponent p is a prime number, Mersenne numbers hold a special place in the never-ending pursuit of larger and larger primes.
- How can you calculate a perfect number from a Mersenne prime?
- The largest known prime is the 40th Mersenne prime: M 20996011 which has 6320430 decimal digits.
- ‘Fermat had this idea that there were families of primes other than Mersenne primes, and there would be an infinite number of them,’ he adds.
- Primes of the form are now known as Mersenne primes, and these numbers figure prominently in the search for the largest known prime.
- In 1876 he used his methods to prove that the Mersenne number 2 127-1 is prime.
- This project is seeking the largest Mersenne prime number, which is, at the moment, also the largest prime number of any form.
- After reading up on how known perfect numbers relate to Mersenne Prime Numbers, I wrote another program, this time to find Mersenne prime numbers and perfect numbers.
- One must be the Lucas Lehmer primality test which uses the Fermat congruence, and in particular his application to testing whether a Mersenne number was prime.
- Usually you download a screensaver or something, and when your computer isn't busy it turns itself on and cranks away at calculating a Mersenne prime or a SETI signal or some other worthy semi-scientific endeavor.
- Primes of the form 2 p - 1 are called Mersenne primes.
- A few months later an engineer at Cray Research discovered a new record Mersenne prime number, and I wrote a 700-word piece describing the discovery.
- The divisor itself is the fifth largest known prime number, and it is the largest that is not a Mersenne prime.
- A computer search turned up the 40th Mersenne prime.
- Expressed in the form 2 p - 1, where the exponent p is itself prime, Mersenne numbers have characteristics that make it relatively easy to determine whether a candidate is prime.
