RSA-140
RSA-140 has 140 decimal digits (463 bits), and was factored on February 2, 1999 by a team led by Herman te Riele and composed of Stefania Cavallar, Bruce Dodson, Arjen K. Lenstra, Paul Leyland, Walter Lioen, Peter L. Montgomery, Brian Murphy and Paul Zimmermann.
The value and factorization is as follows:
