Abstract

In this note we prove the following fact: if finite many elements p1,p2,...,pnp_1,p_2,...,p_n of a unique factorization domain are given such that the greatest common divisor of each pair (pi,pj)(p_i,p_j) can be expressed as a linear combination of pip_i and pjp_j then the greatest common divisor of all pip_is also can be expressed as a linear combination of p1,...,pnp_1,...,p_n. We prove am analogous statement in commutative rings.
