How many ways can N be split into two distinct co-prime factors?

The prime factorization of N! contains all primes which are less than or equal to N. If x is the count of primes less than or equal to N, then the number of ways N! (factorial) can be split into two distinct co-prime factors is equal to 2x – 1.

How many ways can two factors be coprime?

Two factors can be coprime if and only if their greatest common divisor is 1 so which means they would not include a single prime factor in common. As you can see this can go for a while we should use another approach than brute force. No of ways in which other factor can be formed is (3 + 1) x (2 + 1) = 12.
