What two numbers have a GCF of 879?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 879.

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 879. Below is the beginning list of multiples of 879 (1 through 7) in numerical order.

1. 879
2. 1758
3. 2637
4. 3516
5. 4395
6. 5274
7. 6153
etc...

Two numbers that have a GCF of 879 can be 879 and any other number on the list above. Thus, two numbers that have a GCF of 879 are:

879 & 1758
879 & 2637
879 & 3516
etc...

That is not all! Any combination of any multiple of 879 and "odd" multiples of 879 will also have GCF of 879. 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 879.

1758 & 2637
1758 & 4395
3516 & 4395
3516 & 6153
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 879. The lists we created can go on forever.
