|This time, it didn't take a supercomputer. The new record for the largest known prime number goes to someone using a Pentium-powered desktop machine. Joel Armengaud, a computer programmer working for Apsylog in Paris, made the discovery on Nov. 13 and announced it on Nov. 23, after the result had been independently checked by other researchers. The new record holder is (2^1,398,269) - 1, which has 420,921 digits and comfortably beats the previous champion, (2^1,257,787) - 1.|
