Question

Find the GCF of 8cd, 20cd really helpful if someone can give full explanation

Answer 1

GCF: greatest common factor
4 is the biggest number that goes into both 8 and 20 so that is the GCF

Answer 2

A gcf is the biggest number that can be factored out of 2 numbers (divided out of) when we look at 8 and 20 we see that two numbers that they can both be divided by is 2 and 4. 4 is the greatest of the two therefore 4 is your gcf
