WebED implies PID implies UFD. Theorem: Every Euclidean domain is a principal ideal domain. Proof: For any ideal I, take a nonzero element of minimal norm b . Then I must be generated by b , because for any a ∈ I we have a = b q + r for some q, r with N ( r) < N ( b), and we must have r = 0 otherwise r would be a nonzero element of smaller norm ...
