Bezout implies gcd
This article gives the statement and possibly, proof, of an implication relation between two integral domain properties. That is, it states that every integral domain satisfying the first integral domain property must also satisfy the second integral domain property

- Pick two elements in the given Bezout domain. We need to determine their gcd.
- Consider the ideal generated by these two elements. This is a finitely generated ideal, and by the definition of Bezout domain, is a principal ideal. Pick a generator for this principal ideal.
- Show that this generator is indeed the gcd of the two elements.
