Theorem dfgcd3 12446

Description: Alternate definition of the gcd operator. (Contributed by Jim Kingdon, 31-Dec-2021.)

Assertion

Ref	Expression
dfgcd3	|- ( ( M e. ZZ /\ N e. ZZ ) -> ( M gcd N ) = ( iota_ d e. NN0 A. z e. ZZ ( z || d <-> ( z || M /\ z || N ) ) ) )

Distinct variable groups:   M, d, z   N, d, z

Proof of Theorem dfgcd3

Dummy variables a b r w are mutually distinct and distinct from all other variables.
