If we want to determine the number of positive divisors of a small number like 24, we can easily list {1, 2, 3, 4, 6, 8, 12, 24} and count the divisors to see that we have 8 altogether. However, this listing and counting technique is unrealistic for large numbers like 14,000. In this video, you’ll learn how to quickly determine the number of positive divisors of any large number.
