What two numbers have a GCF of 307?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 307.

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 307. Below is the beginning list of multiples of 307 (1 through 7) in numerical order.

1. 307
2. 614
3. 921
4. 1228
5. 1535
6. 1842
7. 2149
etc...

Two numbers that have a GCF of 307 can be 307 and any other number on the list above. Thus, two numbers that have a GCF of 307 are:

307 & 614
307 & 921
307 & 1228
etc...

That is not all! Any combination of any multiple of 307 and "odd" multiples of 307 will also have GCF of 307. 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 307.

614 & 921
614 & 1535
1228 & 1535
1228 & 2149
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 307. The lists we created can go on forever.
