What is a mersume prime number?
Let p = any prime number. (2p -1) is called a Mersenne number. Any such number that is prime is called a Mersenne Prime. Father Mersenne wrote a list of numbers of this type which he thought were prime, but a few were not. In fact, most of the large Mersenne numbers are not prime, but all the really large numbers that have been proved to be prime are Mersenne Primes.
How do you show that 2 and 3 and 5 and 7 are mersenne primes?
The algorithm for a Mersenne prime is 2n - 1, where n is a prime number and the solution is also a prime number.Applying the Mersenne algorithm to the prime numbers 2, 3, 5, and 7:22 - 1 = 3, 23 - 1 = 7, 25 - 1 = 31, and 27 - 1 = 127.3, 7, 32, and 127 all being prime numbers, this demonstrates the 2, 3, 5, and 7 are all Mersenne primes.
How do you test whether a number is a prime or not?
Their are many ways one that some times works is test those answers if prime are Mersenne primes. Or you could google"Is (put the questionable number here)prime?"
What is a Mersenne prime?
A Mersenne Prime is when 2^n-1 is prime. Some examples of a Mersenne Prime are n=2,3,5,7,13,17,19,31,61,89,107, and 127The first forty Mersenne primes are 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, 6972593, 13466917, and 20996011.
Is mersenne prime 1992 even or prime?
1992 is not a Mersenne prime. 1992 is a composite number, being a multiple of 2.
