Science DiscussionsA prime number, sometimes called simply “a prime,” is any natural number that is divisible only by 1 and itself. For example, the prime number “11” is only divisible by “11” and “1.” An infinite number of prime numbers exist. The first twelve prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, and 37. GIMPS (or, Great Internet Mersenne Prime Search) is a volunteer effort that uses free downloadable software from the Internet to search for Mersenne prime numbers. American computer scientist George F. Woltman founded the organization. A Mersenne number (Mn) is a positive integer that is one less than a power (n) of two, or: Mn = 2n -1.
