Example: 30 and 42 Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the highest amount of each factor. 2 x 3 x 5 x 7 = 210, the LCM Multiples of 210 will all be common multiples of 30 and 42 and can be found by multiplying 210 by successive counting numbers. 210 x 1 = 210 210 x 2 = 420 210 x 3 = 630 and so on.

The GCF of 420 and 630 is 210.
