Have you learnt about prime numbers yet? 5 is a prime number so you can't break it up into smaller numbers other than obviously 5*1. 39 is not a prime number. At first glance you should be able to tell that its a multiple of 3 right? 
39=3*13

Now you have smaller numbers.

3*13*5=13*15. 

I guess that's what the answer is.
