# Math Help - Principal Ideal Domain

1. ## Principal Ideal Domain

Hi guys,

Been stuck on this problem for a few days now and still getting nowhere.

Let R be a ring such that Z ⊂ R ⊂ Q.(Z=integers, Q=rationals.) Show that R is a principal ideal domain.

So yeah, was trying to set up a euclidean function but just can't seem to find one that satisfies the conditions. Any suggestions would be greatly appreciated!

Thanks.

2. anyone?
