How do you find the phi of a number?

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.

What numbers make up ϕ 12?

1716 = 11*12*13, φ(1716) = φ(11)*φ(12)*φ(13) = 480. 7480 ≡ 1 mod 1716. φ(13) = 12, 912 ≡ 1 mod 13….Euler's Totient Function and Euler's Theorem.

n	φ(n)	numbers coprime to n
11	10	1,2,3,4,5,6,7,8,9,10
12	4	1,5,7,11
13	12	1,2,3,4,5,6,7,8,9,10,11,12
14	6	1,3,5,9,11,13
