“Largest prime number yet discovered” The biggest prime number yet has been discovered (Wednesday). It is indeed massive, more than 17 million digits long. For those who have been out of school for a while, let's review: A prime number is a positive integer that cannot be divided evenly by any number except itself and 1. The first 10 prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29. The newest find is 2 to the power of 57,885,161 minus 1. That means 2, multiplied by 2 more than 57 million times, minus 1. The lucky number-hunter who came upon it is Curtis Cooper of the Great Internet Mersenne Prime Search (GIMPS). Cooper, a professor at the University of Central Missouri, used his computer to identify the number through software. According to GIMPS, it took 39 days of nonstop computing to prove the prime number is indeed prime. Prime-number hunters do get to reap some rewards. The new number is eligible for a $3,000 prize from GIMPS.
