Answer 1

The answer is 18…………………..

Answer 2

The third prime factor is 5.

Explanation:

What you have so far is 18

You need to multiply 18 by something to get 90

The easiest way about finding out what the fact is is to set up this equation

18*x = 90 Divide by 18

x = 90/18

x = 5 5 is a prime factor, you don't need to break it down.
