What two numbers have a GCF of 387?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 387.

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 387. Below is the beginning list of multiples of 387 (1 through 7) in numerical order.

1. 387
2. 774
3. 1161
4. 1548
5. 1935
6. 2322
7. 2709
etc...

Two numbers that have a GCF of 387 can be 387 and any other number on the list above. Thus, two numbers that have a GCF of 387 are:

387 & 774
387 & 1161
387 & 1548
etc...

That is not all! Any combination of any multiple of 387 and "odd" multiples of 387 will also have GCF of 387. 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 387.

774 & 1161
774 & 1935
1548 & 1935
1548 & 2709
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 387. The lists we created can go on forever.
