Euler's totient function, also known as phi-function ϕ ( n) , counts the number of integers between 1 and n inclusive, which are coprime to n . Two numbers are coprime if their greatest common divisor equals 1 ( 1 is considered to be coprime to any number). Here are values of ϕ ( n) for the first few positive integers: ronald c staffieri
