What two numbers have a GCF of 107?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 107.

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 107. Below is the beginning list of multiples of 107 (1 through 7) in numerical order.

1. 107
2. 214
3. 321
4. 428
5. 535
6. 642
7. 749
etc...

Two numbers that have a GCF of 107 can be 107 and any other number on the list above. Thus, two numbers that have a GCF of 107 are:

107 & 214
107 & 321
107 & 428
etc...

That is not all! Any combination of any multiple of 107 and "odd" multiples of 107 will also have GCF of 107. 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 107.

214 & 321
214 & 535
428 & 535
428 & 749
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 107. The lists we created can go on forever.
