Any Euclidean domain is also a principal ideal domain and therefore also a unique factorization domain. Any Euclidean domain is also a principal ideal domain and therefore also a unique factorization domain.
But even more important, on Euclidean domains we can define gcd and use Euclid's algorithm. But even more important, on Euclidean domains we can define gcd and use Euclid's algorithm.
Examples of Euclidean domains are the rings $\Z$ and the polynomial ring on one variable $F[x]$ where $F$ is a field. Examples of Euclidean domains are the rings $\Z$ and the polynomial ring on one variable $F[x]$ where $F$ is a field.
