Put the number you want to factor at the top. Each successive "branch" breaks the number into factors, then factors of factors. When all the factors are prime, the tree is complete.
Example: 210
210 Divide by two.
105,2 Divide by three.
35,3,2 Divide by five.
7,5,3,2 Stop.
2 x 3 x 5 x 7 = 210
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
There is no factor tree nor factors of 57 as it is a prime number.
IT IS PRIME there is no factor tree
Factor tree of 204
factor tree of 216
The factor tree of 50:5025,25,5,25025,25,5,2

83 is prime. No tree.
The factor tree of 29 would consist of only the number 29 itself, as it is a prime number. Prime numbers have only two factors: 1 and the number itself. Therefore, the factor tree for 29 would simply show 29 at the top with no further branches or factors.
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.
311 is prime. It doesn't need a factor tree.
The factor tree for 148: 148 74,2 37,2,2
