Example: 30 and 42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the common factors.
2 x 3 = 6, the GCF
Gcf you use when you are finding the greatest factor for the numbers. Lcm you use when you are finding the smallest multiple in the numbers factors
You need at least two numbers to find a GCF.
Yes there is
The GCF of these three numbers is 5.
Well, let's take a moment to appreciate these numbers. The greatest common factor, or GCF, is the largest number that divides evenly into all three of these numbers. To find it, we can start by listing the factors of each number and then look for the largest number that appears in all three lists. Remember, there's no rush in finding the GCF, just enjoy the process of exploring these numbers.
