First, tell us what the first factor is, then we'll tell you how to find the other factor. In general, if you take one of the factors out of the prime factorization, the other factor will be left. The prime factorization of 72 is 2 x 2 x 2 x 3 x 3. Suppose one factor was 8. Cover up the 2 x 2 x 2 (8). What's left is 3 x 3 (9). 8 and 9 make up one factor pair of 72.

i dont know what that means does anyone get this"find the greatest common factor of the numbers using prime factorization We'll be eager to jump on it as soon as you give us the numbers.
Numerators and denominators are just numbers; I hope you're not asking us to factor every number. There are many different methods. I prefer to find the prime factorization; that leads to all the other factors. Some people like to use a factor tree to help visualize the prime factorization.
One way to find the prime factorization of a number is to start with the lowest prime number and see if it evenly divides the number. If it does, check whether the result of the division is divisible by that same prime number. When the prime number you are testing does not evenly divide that number, continue with the next prime number. Continue this until the result of the division is a prime number.Check whether 34 is divisible by 2:34 ÷ 2 = 1717 is a prime number, so the prime factorization is finished.The prime factorization of 34 is 2 x 17.Another way to find the prime factorization of a number is to choose a factor pair for that number. Then, find a factor pair for each of those numbers that is not prime.A factor tree of 34 is34/ \2 17Both 2 and 17 are prime, so the tree is finished.The prime factorization of 34 is 2 x 17.
The prime factorization.
You do a factor rainbow to find a prime factorization. You compare prime factorizations to find a greatest common factor.
With a factor tree, yes.
factor tree
If completed correctly, the bottom branch of a factor tree will be the prime factorization of the number at the top.
