The GCF of 12 and 28 is 4.

One way to determine the 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 28 are 1, 2, 4, 7, 14, and 28.

The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4.

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

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

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

The prime factors in common are 2 and 2, so the greatest common factor is 2 x 2 = 4.

Factors of 12: 1 2 3 4 6 12

Factors of 28: 1 2 4 7 14 28
It is 4

What is the greatest common factor of 12 28 and 40?

The greatest common factor of 12, 28, and 40 is 4 To find the greatest common factor of numbers, you first need to split these numbers into their prime factors: 12 = 2x2x3 28 = 2x2x7 40 = 2x2x2x2x5 You then need to find which prime factors are shared between the numbers. In this case, each of the numbers uses two 2s, but no other numbers are common between them. So to find the GCF we simply multiply two 2s: 2x2=4 Thus the GCF of 12, 28 and 40 is 4.
