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
