One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.
The factors of 12 are 1, 2, 3, 4, 6, and 12.
The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84.
The common factors are 1, 2, 3, 4, 6, and 12. Therefore, the greatest common factor is 12.
