What two numbers have a GCF of 800?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 800.

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 800. Below is the beginning list of multiples of 800 (1 through 7) in numerical order.

1. 800
2. 1600
3. 2400
4. 3200
5. 4000
6. 4800
7. 5600
etc...

Two numbers that have a GCF of 800 can be 800 and any other number on the list above. Thus, two numbers that have a GCF of 800 are:

800 & 1600
800 & 2400
800 & 3200
etc...

That is not all! Any combination of any multiple of 800 and "odd" multiples of 800 will also have GCF of 800. 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 800.

1600 & 2400
1600 & 4000
3200 & 4000
3200 & 5600
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 800. The lists we created can go on forever.
