Factor trees are useful when you need to see the factors of a number. It is sometimes easier to see everything spread out.
Factor tree of 40: 40 20,2 10,2,2 5,2,2,2
193 is prime. No tree.
Use a factor tree. 72 36,2 18,2,2 9,2,2,2 3,3,2,2,2
Use a factor tree. 36 18,2 9,2,2 3,3,2,2

use a factor tree
A factor tree is a representation of the process of finding the prime factorization of a given number.
the factor tree for 70 is 70 ^ 10X5 ^ 5X2 SO IT WOULD BE 52
Use a factor tree. 55 5,11
Use a factor tree. 16 8,2 4,2,2 2,2,2,2
you use a factor tree
Their at the bottom of the tree because the hole point of a factor tree is to find the prime factorization of the number, so it would be at the bottom of the tree.
Use a factor tree. 98 49,2 7,7,2
Use a factor tree. 315 105,3 35,3,3 7,5,3,3
