Many thanks!

I actually took "finite mathematics" which dealt mostly with groups, sets and stuff like that, but I totally forgot about it!

So if I understand right, "smooth" works like this:

128 = 2×2×2×2×2×2×2 <- 2 smooth

125 = 5×5×5 <- 5 smooth

120 = 2×2×2×3×5 <- 5 smooth

121 = 11×11 <- 11 smooth

Is it safe to say that you must have the absolute factorization before you can assign a "smooth" value?

I'm not too sure where the "b" is coming from when you mention "b-smooth"...

Finally, what is the correct way to write out a factorization? I've seen it done several ways but I imagine there is an accepted proper way...
