 2020-12-23, 15:34 #1758 James Heinrich     "James Heinrich" May 2004 ex-Northern Ontario 22·839 Posts M19322383 has a 114.614-bit (35-digit) factor: 31779137418604066217200202610865553 (P-1,B1=401000,B2=401000) Biggest P-1 factor of the past 7 days. Also, should have been found by the original P-1 in 2003 but presumably was done with a buggy version of Prime95. Last fiddled with by James Heinrich on 2020-12-23 at 15:53
