RSA-576

In mathematics, RSA-576 is one of the RSA numbers, large semiprimes that are part of the RSA Factoring Challenge. It was factored on December 3 2003 by a team from the German Bundesamt für Sicherheit in der Informationstechnik (BSI, "Federal bureau for security in information technology").

The factorization of RSA-576 is as follows:

RSA-576 = 188198812920607963838697239461650439807163563379417382700763356422988859715234665485319

RSA-576 = 398075086424064937397125500550386491199064362342526708406385189575946388957261768583317

The factorisation was found using the General Number Field Sieve algorithm.
