Best Answer

One way to determine the greatest common factor is to find all the factors of the numbers and compare them.

The factors of 6 are 1, 2, 3, and 6.

The factors of 8 are 1, 2, 4, and 8.

The factors of 12 are 1, 2, 3, 4, 6, and 12.

The common factors are 1 and 2. Therefore, 2 is the greatest common factor.

The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.

The prime factors of 6 are 2 and 3.

The prime factors of 8 are 2, 2, and 2.

The prime factors of 12 are 2, 2, and 3.

The only prime factor they all have in common is 2, so the greatest common factor is 2.
