---------------------------------------------------------------------- Date: Sun, 22 Jun 2003 20:31:04 -0400 From: George Woltman <[EMAIL PROTECTED]> Subject: Mersenne: M997 factored Bruce Dodson has found an incredible 57 digit factor of M997 using prime95's ECM. This is two digits longer than the previous longest factor found using the ECM method. Here's the output from prime95: >ECM found a factor in curve #14, stage #2 >Sigma=6329517009540700, B1=44000000, B2=4290000000. >UID: bd1024tmp, M997 has a factor: >167560816514084819488737767976263150405095191554732902607 >Cofactor is a probable prime!
