Nettetgmp-ecm Elliptic Curve Method for Integer Factorization GMP-ECM reads the numbers to be factored from stdin (one number on each line) and requires a numerical parameter, the stage 1 bound B1. A reasonable stage 2 bound B2 for the given B1 is chosen by default, but can be overridden by a second numerical parameter. NettetF n = 22 n +1 are very good candidates for n 10, since they are too large for general purpose factorization methods. Brent completed the factorization of F 10 and F 11 using ECM, after nding a 40-digit factor of F 10 in 1995, and two factors of 21 and 22 digits of F 11 in 1988 [3].
