What two numbers have a GCF of 1387?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1387.

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 1387. Below is the beginning list of multiples of 1387 (1 through 7) in numerical order.

1. 1387
2. 2774
3. 4161
4. 5548
5. 6935
6. 8322
7. 9709
etc...

Two numbers that have a GCF of 1387 can be 1387 and any other number on the list above. Thus, two numbers that have a GCF of 1387 are:

1387 & 2774
1387 & 4161
1387 & 5548
etc...

That is not all! Any combination of any multiple of 1387 and "odd" multiples of 1387 will also have GCF of 1387. 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 1387.

2774 & 4161
2774 & 6935
5548 & 6935
5548 & 9709
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1387. The lists we created can go on forever.
