Answer 1

To find the greatest common factor (GCF) of 40 and 54, we need to determine the largest number that divides evenly into both numbers. First, we find the factors of each number: 40 = 1, 2, 4, 5, 8, 10, 20, 40 and 54 = 1, 2, 3, 6, 9, 18, 27, 54. The common factors of 40 and 54 are 1, 2. Therefore, the greatest common factor of 40 and 54 is 2.

Answer 2

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

The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.

The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54.

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

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

The prime factors of 40 are 2, 2, 2, and 5.

The prime factors of 54 are 2, 3, 3, and 3.

The prime factors in common are a single 2, so the greatest common factor is 2.
