What two numbers have a GCF of 318?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 318.

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 318. Below is the beginning list of multiples of 318 (1 through 7) in numerical order.

1. 318
2. 636
3. 954
4. 1272
5. 1590
6. 1908
7. 2226
etc...

Two numbers that have a GCF of 318 can be 318 and any other number on the list above. Thus, two numbers that have a GCF of 318 are:

318 & 636
318 & 954
318 & 1272
etc...

That is not all! Any combination of any multiple of 318 and "odd" multiples of 318 will also have GCF of 318. 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 318.

636 & 954
636 & 1590
1272 & 1590
1272 & 2226
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 318. The lists we created can go on forever.
