The number of primitive roots equals the number of generators of the additive group of integers mod 16, which is the Euler totient function of 16, which is 8. Given any primitive root , the primitive roots are , i.e., the odd powers of . 17 is a Fermat prime so the primitive roots are precisely the quadratic nonresidues, see …

WebAnd $$ 2^4\equiv 1\ (15)$$ so that since $4<\phi(15)$, $2$ is not primitive. So we completed by testing six times more, and we concluded that there exists no primitive ... WebThe primitive roots modulo n exist if and only if n = 1, 2, 4, p k, or 2 p k, where p is an odd prime and k is a positive integer. For example, the integer 2 is a primitive root modulo 5 because 2 k ≡ a ( mod 5 ) is satisfied for every integer a that is coprime to 5.
