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.
