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

The factors of 28 are 1, 2, 4, 7, 14, and 28.

The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70.

The common factors are 1, 2, 7, and 14. Therefore, the greatest common factor is 14.

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

The prime factors of 28 are 2, 2, and 7.

The prime factors of 70 are 2, 5, and 7.

The prime factors in common are 2 and 7, so the greatest common factor is 2 x 7 = 14.

The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question! The greatest factor of any number is itself.
