Answer 1

Answer: 6

Explanation:

Well gcf stands for Greatest Common Factor, which basically means 'what is the biggest number that these two numbers can be divided into?'

To start you list all the common factors of 24 and then 30.

24: 1,2,3,4,6,8,12,24

30: 1,2,3,5,6,10,15,30

List the same factors of them both:

1,2,3,6

Answer 2

6

Explanation:

The GCF is the biggest number that you can divide with for both numbers. And 24 divided by 6 is 4, and 30 divided by 6 is 5. You can also see that you cannot simplify 4 and 5 by the same number anymore, proving that 6 is the GCF.
