05.06.2015 · The idea is based on Euler’s product formula which states that the value of totient functions is below the product overall prime factors p of n. The formula basically says that the value of Φ (n) is equal to n multiplied by-product of (1 – 1/p) for all prime factors p of n. For example value of Φ (6) = 6 * (1-1/2) * (1 – 1/3) = 2.

Aug 29, 2021 · A simple solution is to iterate through all numbers from 1 to n-1 and count numbers with gcd with n as 1. Below is the implementation of the simple method to compute Euler’s Totient function for an input integer n. The above code calls gcd function O (n) times. The time complexity of the gcd function is O (h) where “h” is the number of ...

10.09.2019 · Python | sympy.totient () method Last Updated : 17 Sep, 2019 With the help of sympy.totient () method, we can find Euler totient function or phi (n) of a given integer.
