In mathematics, RSA-100 is one of the RSA numbers, large semiprimes that are part of the RSA Factoring Challenge. It was factored in April 1991.

The factorization of RSA-100 is as follows:

RSA-100 = 15226050279225333605356183781326374297180681149613
          37975227936943673922808872755445627854565536638199

RSA-100 = 37975227936943673922808872755445627854565536638199 * 40094690950920881030683735292761468389214899724061
