Re: Factor Numbers
My son has to write at least two ways to break down numbers  I know he did not learn this in school but I would like to help him at home, please help me I have not done this work in over 30 years. He has to break down the numbers 56, 12, 42, 36, 24 and 60. If you can explain to me 1 problem of what they word as a break down, I would be able to do, then follow and figure out the rest. Thank you!

For example, for breaking down 12:
divide by 1, which equals 12
divide by 2, which equals 6
divide by 3, which equals 4
divide by 4, which equals 3
divide by 6, which equals 2
The factors would be 1, 2, 3, 4, 6, 12.
