The Euler totient function 
gives the number of integers smaller than n that are relatively prime to n---that is, that share no common factors with n other than 1. For example, 
because 1, 5, 7, and 11 share no common factors other than 1. If p is a prime number, then 
because all numbers smaller than p are relatively prime to p.
gives the number of integers smaller than n that are relatively prime to n---that is, that share no common factors with n other than 1. For example, because 1, 5, 7, and 11 share no common factors other than 1. If p is a prime number, then because all numbers smaller than p are relatively prime to p.Write a function to compute the Euler totient function.
Note: I now realize that Cody Problem 656 also deals with the totient function. Apologies to Freddy.
