Write 360 as a product of its prime factors

The general method for finding a prime factorization is to look at the number and start dividing out low numbers that are obvious. I'll show you how I do this for the number 360:

I see that it is an even number, so I can factor out a 2 :

360 = 2 * 180

Now 180 is also even, so I factor out another 2 :

360 = 2 * 2 * 90

Now 90 is also even, so I factor out ANOTHER 2 :

360 = 2 * 2 * 2 * 45

Now I have a 45 to deal with, and that is (3 * 15), so write it that way :

360 = 2 * 2 * 2 * 3 * 15

Now 15 can be factored as (3 * 5), and there are no lower prime factors, so I'm done :

360 = 2 * 2 * 2 * 3 * 3 * 5

and usually instructors like to see it written in exponent form :

360 = (2)^3 * (3)^2 * 5

40%=2/550=1/230=3/1056=14/25
