A factor tree is a diagram used to break- up a number by dividing it equally and show you all the different parts of the number.
ex. 18
9 x 2
3 x 3
Then you would multiply the simple numbers or the numbers that can't be divided anymore of them: 3 x 3 x 2 =18.
Some links to other questions with examples of factor trees are given below.
and that is the defention of a factor tree or example
IT IS PRIME there is no factor tree
The factor tree of 50:5025,25,5,25025,25,5,2
21
The factor tree for 148: 148 74,2 37,2,2
Factor tree for 49:49/ \7 x 7497,7
factor tree of 216
IT IS PRIME there is no factor tree
Factor tree of 204
The factor tree of 50:5025,25,5,25025,25,5,2

83 is prime. No tree.
The prime factor tree of 280 is:140,270,2,235,2,2,27,5,2,2,2
Factor Tree of 20: ........20 ......../ \ .......4 5 ....../ \ .....2 2
A tree.
The factor tree for 148: 148 74,2 37,2,2
311 is prime. It doesn't need a factor tree.
NEVER! A factor tree is strictly division. Factors at the end of a factor tree should all be whole numbers.
