One way to determine the greatest common factor is to find all the factors of the numbers and compare them.
The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.
The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.
The factors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56.
The common factors are 1 and 2. Therefore, 2 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 30 are 2, 3, and 5.
The prime factors of 42 are 2, 3, and 7.
The prime factors of 56 are 2, 2, 2, and 7.
The prime factors in common are a single 2, so the greatest common factor is 2.
