A noetherian integral domain is a ufd if and only if every height 1 prime ideal is principal (a proof is given at the end). also, a dedekind domain is a ufd if and only if its ideal class group is trivial. in this case, it is in fact a principal ideal domain. in general, for an integral domain a, the following conditions are equivalent: a is a ufd. A unique factorization domain, called ufd for short, is any integral domain in which every nonzero noninvertible element has a unique factorization, i.e., an essentially unique decomposition as the product of prime elements or irreducible elements. in this context, the two notions coincide, since in a unique factorization domain, every irreducible element is prime, whereas the opposite. An integral domain r is called a unique factorization domain (or ufd) if the following conditions hold. every nonzero nonunit element of r r. is either irreducible or can be written as a finite product of irreducibles in r. r. factorization into irreducibles is unique up to associates. that is, if s ∈ r s ∈ r. can be written as.

Actually, you should think in this way. ufd means the factorization is unique, that is, there is only a unique way to factor it. for example, in $\mathbb{z}[\sqrt5]$ we have $4 =2\times 2 = (\sqrt5 1)(\sqrt5 1)$. here the factorization is not unique. In frayleigh the definition of an ufd (unique factorization domain) is the following: an integral domain $d$ is a unique factorization domain if the following.
