abstract algebra - Fermat's Little theorem to find primes

---

Find $4$ primes that divide
$14^{60} - 33^{60}$

---

okay, so the easiest thing to do was to re-write that as $7^{60}2^{60} - 11^{60}3^{60}$.
However, that doesn't really help.
Next step is the little Fermat's theorem, makes sense to try with modulo $2, 3, 7, 11$. However I don't remember how to do that, how to start. Would appreciate any help.
