109 109 x 1 This is all there is to the factor tree, because 109 is a prime number. Normally, I wouldn't use 1 in a factor tree, but I do in this case to make it clear that I have done a factor tree, since 109 is only divisible by itself and 1.

IT IS PRIME there is no factor tree
The Greatest Common Factor (GCF) is: 7
The factor tree of 50:5025,25,5,25025,25,5,2
212/2 106// 2 2 53///
Because 45 is not a factor of 60.
NEVER! A factor tree is strictly division. Factors at the end of a factor tree should all be whole numbers.
The GCF of 68 and 212 is 4.
All factors of a number
When the bottom branch consists entirely of prime numbers.

Use a factor tree. 221 13,17 All the factors are prime. 13 x 17 = 221
