How do you find the greatest common factor of 24, 28?
1 Answer
Find the prime factorization for both numbers and multiply all common factors.
Explanation:
You could find the prime factorizations of
#24 = 2^2 * 3#
#28 = 2^2 * 7#
We see that
#2^2 = 4#
There are other ways to find the GCF as well such as listing out all the factors of each number and picking out the greatest, which is a little more tedious and unnecessary.
