How do you make a factor tree?

Answer 1

You can easily make a factor tree by dividing the number in half. This strategy is useful if the number is divisible by 2.

112- a number where you cant think of immediate factors

divide it in 2:

56,2

again:

28,2,2

14,2,2,2

7,2,2,2,2

7 is prime, making this tree complete.

If the number isn't divisible by 2 that it could become more complicated. most of the time, you can find a factor quickly and then just begin dividing in half.
