What two numbers have a GCF of 1120?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1120.

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 1120. Below is the beginning list of multiples of 1120 (1 through 7) in numerical order.

1. 1120
2. 2240
3. 3360
4. 4480
5. 5600
6. 6720
7. 7840
etc...

Two numbers that have a GCF of 1120 can be 1120 and any other number on the list above. Thus, two numbers that have a GCF of 1120 are:

1120 & 2240
1120 & 3360
1120 & 4480
etc...

That is not all! Any combination of any multiple of 1120 and "odd" multiples of 1120 will also have GCF of 1120. 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 1120.

2240 & 3360
2240 & 5600
4480 & 5600
4480 & 7840
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1120. The lists we created can go on forever.
