Number of divisors of a number formula
Web6 apr. 2024 · The count of divisors will be (i 1 + 1) * (i 2 + 1) * … * (i k + 1). It can now be seen that there can only be one prime divisor for the maximum i and if N % pi = 0 then (i + 1) should be prime. The primality can be checked in sqrt (n) time and the prime factors can also be found in sqrt (n) time.
