GCF of 28 42 and 56 is 14.The GCF is 14.(28 = 2 x 14, 42 = 3 x 14, 56 = 4 x 14)To find the GCF, factor the numbers and multiply their common prime factors:28 = 2 x 2 x 742 = 2 x 3 x 756 = 2 x 2 x 2 x 7Common factors are 2 x 7 = 14
An interesting trick is to subtract the two numbers, as follows: For example, the GCF of 14 and 10 is the same as the GCF of 10 and 4, where 4 is the result of the subtraction. Instead of subtracting several times, you can also get the remainder of a division: 10 divided by 4 gives a remainder of 2.
