You only have to go as far as you want, of course. If you want to go up to A * A, fine. If you want to go to C * C, great. There's no reason to go to precisely 10 * 10 in the given base.

If I ever need to factor a semiprime coprime to 6 with at most 2 decimal digits, I'll know where to turn to -- assuming your method can handle the other eight candidates.
