In mathematics, RSA-140 is one of the RSA numbers, large semiprimes that are part of the RSA Factoring Challenge. It was factored on February 2 1999 by a team led by Herman J. J. te Riele and comprised of Stefania Cavallar , Bruce Dodson , Arjen K. Lenstra , Paul Leyland , Walter Lioen , Peter Montgomery , Brian Murphy and Paul Zimmermann .
The factorization of RSA-140 is as follows:
RSA-140 = 2129024631825875754749788201627151749780670396327721627823338321538194

RSA-140 = 3398717423028438554530123627613875835633986495969597423490929302771479

The factorisation was found using the Number Field Sieve algorithm and an estimated 2000 MIPS-years of computing time.
