Shouldn't it be factor(1)?

It's been _many_ years since I did any _real_ math, so if you would like me to use a faster method, I may need some clues (I will have _no_ problem optimizing an algorithm to C, but may not see if there is a better way mathamatically) (I might be over-stating my lack of experience somewhat). :) Max ----- Max Euston <meuston@jmrodgers.com> Sysadm, Programmer, etc...
