how do i do gcf? like an easy way

Answer 1

look for the maximum common thing among terms.

Answer 2

A method for finding the greatest common factor is to list the prime factors, then multiply the common prime factor

Example: Find the GCF of 36 and 54

the prime factorizations of 36 and 54 are

Notice that the prime factorizations of 36 and 54 both have one 2 and two 3's in common. So, we simply multiply these common prime factors to find the greatest common factor:

GCF=2 * 3 * 3 = 18
