WebMar 11, 2024 · Euler's totient function. 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: Web1st step. To find the number of positive integers less than or equal to 180 that are relatively prime to 180, first consider the prime factorization of 180, which is 180 = 2 2 × 3 2 × 5. Use the principle of inclusion-exclusion to count the number of integers that are not relatively prime to 180. Let A be the set of integers less than or ...
