Curtis Cooper, a mathematician and computer science professor at theÂ University of Central Missouri, has discovered the largest knownÂ prime numberÂ to date on January 25. Several people verified the discovery using different hardware and software by the beginning of February and it was announced on Tuesday. Cooper found the prime as a participant in theÂ distributed computingÂ project known as theÂ Great Internet Mersenne Prime Search, or GIMPS. Cooper runs the GIMPS client, calledÂ Prime95, on an estimated 1,000 computers at the university.
A prime number is a positive integer greater than 1 that can only be evenly divided by 1 and itself. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17 and 19. 77 (for example) is not prime because it is a product of 7 and 11. The newly discovered prime is expressed as 257,885,161Â âˆ’ 1 and has 17,425,170 digits. It is a specific type of prime number called aÂ Mersenne prime, which are of the form 2pÂ âˆ’ 1.

George WoltmanÂ developed and founded GIMPS, the longest known continuously running computer project, in 1996. Cooper as a participant had previously discovered two other Mersenne primes, 230,402,457Â âˆ’ 1 in December 2005 and 232,582,657Â âˆ’ 1 in September 2006, with fellow professor Steven Boone. This latest discovery ends an intermission of almost four years; the previous Mersenne prime was found in April 2009.
