What two numbers have a GCF of 247?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 247.

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 247. Below is the beginning list of multiples of 247 (1 through 7) in numerical order.

1. 247
2. 494
3. 741
4. 988
5. 1235
6. 1482
7. 1729
etc...

Two numbers that have a GCF of 247 can be 247 and any other number on the list above. Thus, two numbers that have a GCF of 247 are:

247 & 494
247 & 741
247 & 988
etc...

That is not all! Any combination of any multiple of 247 and "odd" multiples of 247 will also have GCF of 247. 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 247.

494 & 741
494 & 1235
988 & 1235
988 & 1729
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 247. The lists we created can go on forever.
