What two numbers have a GCF of 7638?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 7638.

There is actually an infinite number of answers to this question. First, note that both the numbers we are looking for must be multiples of 7638. Below is the beginning list of multiples of 7638 (1 through 7) in numerical order.

6. 45828
7. 53466
etc...

Two numbers that have a GCF of 7638 can be 7638 and any other number on the list above. Thus, two numbers that have a GCF of 7638 are:

7638 & 15276
7638 & 22914

etc...

That is not all! Any combination of any multiple of 7638 and "odd" multiples of 7638 will also have GCF of 7638. We numbered the multiples above so it would be easy to identify the "odd" multiples (number 1, 3, 5, 7, etc). Thus, here are some more examples of two numbers that also have a GCF of 7638.

15276 & 22914
15276 & 38190
