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 30 are 1, 2, 3, 5, 6, 10, 15, and 30.

The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80.

The common factors are 1, 2, 5, and 10. Therefore, the greatest common factor is 10.

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

The prime factors of 30 are 2, 3, and 5.

The prime factors of 80 are 2, 2, 2, 2, and 5.

The prime factors in common are 2 and 5, so the greatest common factor is 2 x 5 = 10.
