Classically, divisibility, ideal and valuation theory are three different approaches to the study of multiplication in certain algebraic number rings. In this talk we emphasise the importance of Gauss' Lemma in valuation theory and sharpen
Eisenstein's ctriterion. Divisibility theory provides a unified way to work in a bigger class of rings containing both domains and Boolean algebras.
