The greatest common factor is 2. First, you can list all the factors of 4. 1, 2, 4 Next, list all the factors of 10: 1, 2, 5, 10 Now, look back at the two lists and see if any of the numbers are the same in both lists. If there is more than one, the greatest number will be the greatest common factor. In this case, the only common number is 2, and so it is automatically the greatest common factor.
