Did you mean what Mersenne numbers are prime? If a number is a prime, how is it not a prime at the same time? Anyways, M11, or (2^11) - 1, I think is the lowest Mersenne Number Mp that isn't prime, when p is prime. Any Mersenne Number where p is not prime cannot be prime.

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.
What are Mersenne Primes used for?
Mersenne primes are mostly of interest as mathematical curios. A Mersenne prime has the form 2n-1. For 2n-1 to be prime, n must also be prime. Perfect numbers have the form 2n-1(2n-1) where 2n-1 is a Mersenne prime, so when a new Mersenne prime is discovered, another perfect number is also found.
What category of primes is the largest prime?
Mersenne prime is the largest known prime number
What are the first four mersenne prime?
The first four Mersenne primes are 2, 3, 5, and 7.
How many Mersenne prime numbers are there?
It is, as of now, an open question whether there are a finite or an infinite number of Mersenne primes. At the beginning of the 21st century there were 47 known Mersenne primes, the highest being 43,112,609.
What is the 48th mersenne prime?
As of the current date, November 2011, only forty-seven Mersenne primes are known.
What is the largest known mersenne prime?
There were 47 known Mersenne primes at the beginning of the 21st century, the highest being 43,112,609.

What are some Mersenne numbers?
A Mersenne number is a number that can be written as 2n - 1. A Mersenne prime is a Mersenne number that is a prime number. Here are some Mersenne primes: 22 - 1 = 3 23 - 1 = 7 25 - 1 = 31 27 - 1 = 127
What is the difference of mersenne prime and a prime number?
A prime number has only two factors, 1 and itself. A Mersenne prime is a prime number derived from the algorithm 2n - 1. For example, 23 - 1 = 7 and 7 is a prime number so 3 is a Mersenne prime. Similarly 27 - 1 = 127 and 127 is a prime number so 7 is a Mersenne prime. There are 47 known Mersenne primes, the highest being 43,112,609.

Is 199 a mersenne prime?
199 is not a Mersenne prime because it does not fit the algorithm 2n - 1. 2199 - 1 = does not produce a prime number. The Mersenne primes below 200 are 2, 3, 5, 7, 13, 17, 19, 31, 61, 89, 107, and 127.
What is merssene prime numbers?
Mersenne primes are the primes of the form 2^p-1 where p is a prime. These start 2^2-1 = 3, 2^3-1 = 7, 2^5-1 = 31.
