Algorithm to calculate the number of divisors of a given number

...ivisor is repeated) then the total count for all of the divisors is: (x + 1) * (y + 1) * (z + 1). Edit: BTW, to find a,b,c,etc you'll want to do what amounts to a greedy algo if I'm understanding this correctly. Start with your largest prime divisor and multiply it by itself until a further multip...
