what's the prime factorization of 525?
and factorization of 216?

293 is already a prime number.

Start dividing 525 by 5^2, leaving you with 21. You should recognize the prime factors of that.

Start be dividing 216 by 2^3, leaving you with 27. That looks like 3^3 to me. So the answer in that case is 2^3 * 3^3
