(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

If R = Z_{n}, show that every ideal of R has the form mR for some integer m.

2. Relevant equations

3. The attempt at a solution

Well, by a previous problem I showed mR is the principal ideal of the ring, but I don't know if that's relevant. I was given the hint to try to use GCDs somehow, but I really have no ideas.

thanks so much!
