Theorem dvdsprime 12883

Description: If M divides a prime, then M is either the prime or one. (Contributed by Scott Fenton, 8-Apr-2014.)

Assertion

Ref	Expression
dvdsprime	|- ( ( P e. Prime /\ M e. NN ) -> ( M || P <-> ( M = P \/ M = 1 ) ) )

Proof of Theorem dvdsprime

Dummy variable m is distinct from all other variables.
