i can't remember for the formula for it, but does anyone happen to know a quick way to determine the total # of positive factors?
for example, trying to find them for the number 441. i would first go about this by breaking 441 into prime numbers, yielding 7, 7, 3, and 3. there are a total of 9 different factors of 441, which results from these primes. does anyone know a fast way to find this total number of 9 without having to go through all of the different combinations?
this could become quite tedious with bigger numbers.
thanks!
