The GCF of 12 and 42 is 6.
The greatest common factor can be calculated by identifying the common prime factors and multiplying them together.
12 = 2 x 2 x 3
42 = 2 x 3 x 7
The GCF of 12 and 42 is: 2 x 3 = 6
Another way to determine the greatest common factor is to find all the factors of the numbers and compare them.
The factors of 12 are 1, 2, 3, 4, 6, and 12.
The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.
The common factors are 1, 2, 3, and 6. Therefore, the greatest common factor is 6.
