What two numbers have a GCF of 591?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 591.

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 591. Below is the beginning list of multiples of 591 (1 through 7) in numerical order.

1. 591
2. 1182
3. 1773
4. 2364
5. 2955
6. 3546
7. 4137
etc...

Two numbers that have a GCF of 591 can be 591 and any other number on the list above. Thus, two numbers that have a GCF of 591 are:

591 & 1182
591 & 1773
591 & 2364
etc...

That is not all! Any combination of any multiple of 591 and "odd" multiples of 591 will also have GCF of 591. 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 591.

1182 & 1773
1182 & 2955
2364 & 2955
2364 & 4137
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 591. The lists we created can go on forever.
