Explain all the steps to factor a number using a factor tree.

1. write down the number.... say 12

2. think of factors of 12 such as 6 x 2
3. now your tree looks like
12
/ \
6 2 but since 2 cant be factored any more its branch ends
/ \ and the 6 can now be broken down further to 3x2
3 2
and you see that 12 = 3 x 2 x 2
