A factor tree is a way to notate the process of finding the prime factorization of a given number.
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.
Example: 210
210 Divide by two.
105,2 Divide by three.
35,3,2 Divide by five.
7,5,3,2 Stop. All the factors are prime.
2 x 3 x 5 x 7 = 210
That's the prime factorization of 210.
A factor tree is a notation of the process of finding the prime factorization of a given number.
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
21
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.
