GcdDomain

catdef.spad line 688 [edit on github]

This category describes domains where ``gcd` can be computed but where there is no guarantee of the existence of :spadfun:`factor operation for factorization into irreducibles. However, if such a factor operation exist, factorization will be unique up to order and units.
