To determine the greatest common
To determine the greatest common factor (GCF) of 12 and 20, we will list the factors for each number and then identify the greatest common factor between them. Here's the step-by-step process:
Step 1: List the Factors of 12
The factors of 12 are the numbers that can evenly divide 12. In this case, they are 1, 2, 3, 4, 6, and 12.
Step 2: List the Factors of 20
The factors of 20 are the numbers that can evenly divide 20. In this case, they are 1, 2, 4, 5, 10, and 20.
Step 3: Identify the Common Factors
By comparing the lists of factors for 12 and 20, we can find the common factors, which are the numbers that appear in both lists.
Common Factors: 1, 2, 4
Step 4: Determine the Greatest Common Factor
Finally, to find the GCF, we need to determine which common factor is the greatest. In this case, the greatest common factor of 12 and 20 is 4.
So, the GCF of 12 and 20 is 4.
Note: The GCF is 4 because it is the highest factor that both 12 and 20 share.

By comparing the lists of factors for 12 and 20, we can find the common factors, which are the numbers that appear in both lists.
Common Factors: 1, 2, 4
Step 4: Determine the Greatest Common Factor
Finally, to find the GCF, we need to determine which common factor is the greatest. In this case, the greatest common factor of 12 and 20 is 4.
So, the GCF of 12 and 20 is 4.
Note: The GCF is 4 because it is the highest factor that both 12 and 20 share.
