Abstract. We give details of the factorization of RSA-704 with CADO-NFS. This is a record computation with publicly available software tools. The aim of this experiment was to stress CADO-NFS — which was originally designed for 512-bit factorizations — for larger inputs, and to identify possible rooms of improvement. We report on the factorization of RSA-704 (212 decimal digits), which is the 2nd largest integer factorization with the General Number Field Sieve (GNFS), after the factorization
