What two numbers have a GCF of 891?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 891.

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 891. Below is the beginning list of multiples of 891 (1 through 7) in numerical order.

1. 891
2. 1782
3. 2673
4. 3564
5. 4455
6. 5346
7. 6237
etc...

Two numbers that have a GCF of 891 can be 891 and any other number on the list above. Thus, two numbers that have a GCF of 891 are:

891 & 1782
891 & 2673
891 & 3564
etc...

That is not all! Any combination of any multiple of 891 and "odd" multiples of 891 will also have GCF of 891. 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 891.

1782 & 2673
1782 & 4455
3564 & 4455
3564 & 6237
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 891. The lists we created can go on forever.
