A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common.

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

The factors of 18 are 1, 2, 3, 6, 9, and 18.

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

The factors of 81 are 1, 3, 9, 27, and 81.

The common factors are 1, 3, and 9. Therefore, the greatest common factor is 9.
