Witryna1 Answer. If R is UFD, then R [ X] is UFD (see any textbook). If R is UFD and f ∈ R ∖ { 0 }, then R [ 1 f] is UFD. The prime elements are those of R which don't divide f. Proof: They are prime because of the classification of prime ideals of localizations. If 0 ≠ a ∈ R [ 1 f], say a = x / f k, then x is a product of prime elements.
