This week I have learnt about factor trees. When I do factor trees I normally start by dividing the number by 2 so if the number was 44, the two numbers under it would be 2 and 22. Then since 2 is a prime and it can't be divided by anything you have to divide 22. Again 22 can be divided 2 so the next to numbers under 22 will be 2 then 11. Now since both 2 and 11 are prime numbers you have to finish the tree there.
