To the best of my knowledge there's no Java built-in function that computes φ. However, if you look at what's being said here, you're given a direct way to compute it: φ (pq) = (p - 1) (q - 1), so computing φ (n) is equivalent to computing (p - 1) (q - 1) if you know the values of p and q.

WebThe Euler's totient function, or phi (φ) function is a very important number theoretic function having a deep relationship to prime numbers and the so-called order of integers. The totient φ(n) of a positive integer n greater than 1 is defined to be the number of positive integers less than n that are coprime to n. WebThe Euler's Totient Function counts the numbers lesser than a number say n that do not share any common positive factor other than 1 with n or in other words are co-prime with n. For 8 : 1 and 8 are co-prime as the only common factor is 1 itself. 2 and 8 have a common factor 2. 3 and 8 are co-prime.
