A Prime number has two factors, 1 and itself. 1 is not considered a prime number as its factors are 1. Following the rule for primes, you could say that its factors are 1 and 1, but 1 and 1 are obviously the same number.

What mersenne primes aren't prime?
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.
