What two numbers have a GCF of 1231?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1231.

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 1231. Below is the beginning list of multiples of 1231 (1 through 7) in numerical order.

1. 1231
2. 2462
3. 3693
4. 4924
5. 6155
6. 7386
7. 8617
etc...

Two numbers that have a GCF of 1231 can be 1231 and any other number on the list above. Thus, two numbers that have a GCF of 1231 are:

1231 & 2462
1231 & 3693
1231 & 4924
etc...

That is not all! Any combination of any multiple of 1231 and "odd" multiples of 1231 will also have GCF of 1231. 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 1231.

2462 & 3693
2462 & 6155
4924 & 6155
4924 & 8617
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1231. The lists we created can go on forever.
