--- Definition: Euler's Totient Function, denoted by φ(n), is defined as the number of positive integers less than n that are relatively prime (coprime) to n. Two numbers are relatively prime if their greatest common divisor (GCD) is 1. Special Property: If n is a prime number, then: φ(n) = n - 1...
