Math Whizzes find Prime Number with 13 Million Digits!

Mathematicians at UCLA have discovered a 13-million digit prime number, a long-sought milestone that makes them eligible for a $100,000 prize. The group found the 46th known Mersenne prime last month on a network of 75 computers running Windows XP. The number was verified by a different computer system running a different algorithm.

Primes are numbers like three, seven, and 11 that are divisible by only two whole positive numbers: themselves and one. Mersenne primes are named for their discoverer, 17th century French mathematician Marin Mersenne. Thousands of people around the world have been participating in the Great Internet Mersenne Prime Search or GIMPS.
