WebFeb 11, 2016 · If r does not divide (p − 1) then p − 1 = qr + R for some remainder R satisfying 0 < R < r. Then gp − 1 = gqrgR ≡ 1 ⋅ gR (mod p). By Fermat's Little Theorem, we know that gp − 1 ≡ 1 mod p, so we see that gR ≡ 1 (mod p). But this contradicts the fact that r is the order of g, as R < r.

In this k = 4 is a solution. Since 3 16 ≡ 1 (mod 17), it also follows that if n is an integer then 3 4+16n ≡ 13 x 1 n ≡ 13 (mod 17). Therefore, the equation has infinitely some solutions of the form 4 + 16n. charlie guffey law cookeville tn
