What is the greatest common factor of 12 and 4?

Answer 1

If the larger number is a multiple of the smaller number, as in this case, the GCF is the smaller number. (Alternatively, using Euclid's algorithm, the remainder of the division of the larger number by the smaller number is zero, so in this case, the GCF of 12 and 4 is the same as the GCF of 4 and 0 - which is equal to 4.)

Answer 2

There can only be one "greatest".

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

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

The common factors are: 1, 2, and 4.

The greatest common factor is 4 .

Answer 3

The GCF of 4 and 12 is 4. As 12 is a multiple of 4, the GCF of the pair is 4.

Answer 4

The highest common factor (not common highest factor) of 4 and 12 is 4.
