What two numbers have a GCF of 291?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 291.

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 291. Below is the beginning list of multiples of 291 (1 through 7) in numerical order.

1. 291
2. 582
3. 873
4. 1164
5. 1455
6. 1746
7. 2037
etc...

Two numbers that have a GCF of 291 can be 291 and any other number on the list above. Thus, two numbers that have a GCF of 291 are:

291 & 582
291 & 873
291 & 1164
etc...

That is not all! Any combination of any multiple of 291 and "odd" multiples of 291 will also have GCF of 291. 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 291.

582 & 873
582 & 1455
1164 & 1455
1164 & 2037
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 291. The lists we created can go on forever.
