How to express in terms of prime factors

[Misfire]

I'm reading an explanation to a GRE math question, and I'm stumped.

The problem starts with this:

z= 15^3 * 14^5 * 27^3

The answer explanation says to "first rewrite the numbers in terms of prime factors." Could someone show me know how to do this?

take the prime factors of 15, 14, and 27

so it would be (3*5)^3 * (2*7)^5 * 3^9

so 3^12 * 5^3 * 2*5 * 7^5

Thanks!
