the current implementation of factor is laughably bad; consider using Floyd's cycle-finding algorithm with Brent's algorithms to somehow faciliate optimised Pollard's rho algorithm. It seems to be what coreutils do (+ trial division i guess), except I can't be bothered to check what kind of cycle finding algorithm do they use, since the code is, as usual for GNU, obfuscated.
