In number theory, Euler's totient function counts the positive integers up to a given integer n that are relatively prime to n. It is written using the Greek letter phi as φ(n) or ϕ(n), and may also be called Euler's phi function. Write a Python program to calculate Euclid's t...
Ifppandrrare relatively prime you useEuler's theorempϕ(r)=1pϕ(r)=1modrr. So you need to calculateq!q!modϕ(r)ϕ(r).ϕϕis theEuler totient function, for a primerrit is justr−1r−1. You can find the answer even if(p,r)>1(p,r)>1, but it involves additional ...
