What's a good memory efficient way to get all the divisors of a number? right now I'm looking at performing a 'for' loop and check each integer between 1 and the number I'm putting in and storing the divisors into a list, but for large numbers this is slow and/or causes stack heaps.

ah, I forgot about that basic theorem of divisor pairs having one that is less than (or equal to) the square root of the number.
