Stein, S.; Szabó, S. Elementary infinite sources of non-unique factorization rings. (English) Zbl 0813.13015 Am. Math. Mon. 101, No. 8, 769-770 (1994). When students first meet unique-factorization rings, they may get the impression that non-unique-factorization rings are rare. We offer an infinite number of such rings. We describe two ways to do this.
