How do you use prime factorization to find the GCF of three numbers?
You can find the prime factors of all three numbers, combine (multiply) those numbers and remove redundant factors. So if your numbers are 4, 6 and 8, then those factors are (2*2), (3*2), and (2*2*2) respectively. The GCF is 24 or (2*2*2*3). This is because 24 can be written as a multiple of all three numbers because 24 can be written as a multiple of 2 4 and 6. (2*2*3*(2)) (2*3*(4)) and (2*2*(6)). If this is still unclear you can check the Wikipedia Article on LCM.
What 3 numbers multiplied get 720?
Well, isn't that a happy little math problem! To find three numbers that multiply to 720, we can start by breaking down 720 into its prime factors: 2 x 2 x 2 x 3 x 3 x 5. Then, we can group these factors into three numbers, like this: 2 x 2 x 180, which equals 720. So, the three numbers are 2, 2, and 180.
