Answer:

Step-by-step explanation:

Factor both numbers into their prime factors. Then pick the numbers that are in both.

42: 2*3*7

63:3*3*7

Which numbers are in both rows.

3 and 7

One more example would be good.

Suppose the two numbers were

45: 3*3 * 5

63:3 *3 * 7

In this example, there are two threes in both numbers. Both of them must be used for the GCF: 3*3 = 9

The GCF = 21 for your question.
