Question

I need help with this problem on my test and the question. Says which pairs of numbers, have a GCF of 12 and I am really stuck on it I was gone that day so it's not done so please help me really quick so I can get it done

Answer 1

do you have a list to choose from ?

there are infinitely many pairs of numbers that have 12 for a GCF

12 and 24

12 and 36

24 and 36

36 and 60

48 and 84

to get more pairs simply multiply 12 by any two numbers that are relatively prime (numbers that do not have any common factors except the number 1)

try 3 and 8; 36 and 96

try 5 and 6; 60 and 72
