What two numbers have a GCF of 126?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 126.

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 126. Below is the beginning list of multiples of 126 (1 through 7) in numerical order.

1. 126
2. 252
3. 378
4. 504
5. 630
6. 756
7. 882
etc...

Two numbers that have a GCF of 126 can be 126 and any other number on the list above. Thus, two numbers that have a GCF of 126 are:

126 & 252
126 & 378
126 & 504
etc...

That is not all! Any combination of any multiple of 126 and "odd" multiples of 126 will also have GCF of 126. 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 126.

252 & 378
252 & 630
504 & 630
504 & 882
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 126. The lists we created can go on forever.
