Find Aut(Z ₁₅). Use the Fundamental Theorem of Abelian Groups to express this group as an external direct product of cyclic groups of prime power order. (Thank you. If any theorems. corollaries, definitions, etc. are related, I'd appreciate the extra knowledge. If you don't have time, I understand and thanks, anyway.
