3 x 7 x 7 x 11 x 13
A Factor tree looks like this:... 42... / . \..2 ...21....... / . \.......3 . 7So the prime factors of 42 are 2 x 3 x 7
83 is prime. No tree.
The purpose of a factor tree is to divide a number into prime factors. 1 is not a prime number.
When the bottom branch consists entirely of prime numbers.
167 is already prime. No need for a tree.
3x7=21 3 and 7 are prime numbers, so 3x7 is the factor tree of the number 21.
21 3,7 3 x 7 = 21
A Factor tree looks like this:... 42... / . \..2 ...21....... / . \.......3 . 7So the prime factors of 42 are 2 x 3 x 7
21
83 is prime. No tree.
IT IS PRIME there is no factor tree
The purpose of a factor tree is to notate the process of finding the prime factorization. If a number is already prime, a factor tree is not necessary.
Prime Factor Tree: ........452 ........./ \ .......4 113 ....../ \ ....2...2
The prime factor tree of 280 is:140,270,2,235,2,2,27,5,2,2,2
factor trees and prime factor trees are the same thing with different names.
21 = 3 x 7. Both these factors are prime.
199 is a prime number. It does not have a tree since it only has one prime factor, itself.
