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

The factors of 27 are 1, 3, 9, and 27.

The factors of 51 are 1, 3, 17, and 51.

The common factors are 1 and 3. Therefore, 3 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 27 are 3, 3, and 3.

The prime factors of 51 are 3 and 17.

The common prime factors are a single 3, so 3 is the greatest common factor. 3

The GCF is 3.
