| | Mersenne: M673 Factored by NFSNET |
 | | On March 17th 2003, NFSNET completed the factorization of 2^673-1. |
 | | The factors of the C151 cofactor are: p59 = 68396769572915971687133122358352070840260017483089158059519 and P92 = 23882525111457526669660263269125438250762730250942712633131 \ 193354954889195068879706608493409 Numbers of the form 2^n-1 are known as Mersenne numbers and 2^673-1 was the smallest Mersenne number whose complete factorization was unknown. |
 | | The NFSNET administrators: Chris Card Jeff Gilchrist Don Leclair Paul Leyland Richard Wackerbarth Contributors to the 2^673-1 factorization: Brian Beesley, Chris Card, Jeff Gilchrist, Francois Grieu, Alex Kruppa, Rick Lavoie, Don Leclair, Paul Leyland, Igor Schein, Martin Schroeder, Richard Wackerbarth and 18 others who have not selected to be listed here. |
