A pair of numbers has a GCF of 6 and a LCM of 60. What could the numbers be? Explain.

(2*3)=6; 60= (2*3)*2*5 (prime factorization)

The numbers in the parenthesis can't be taken out because they are the HCF

So just move the 2 and the 5 on both sides and you'll get two pairs that are (6,30) and (12,30)

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
