What two numbers have a GCF of 1098?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1098.

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 1098. Below is the beginning list of multiples of 1098 (1 through 7) in numerical order.

1. 1098
2. 2196
3. 3294
4. 4392
5. 5490
6. 6588
7. 7686
etc...

Two numbers that have a GCF of 1098 can be 1098 and any other number on the list above. Thus, two numbers that have a GCF of 1098 are:

1098 & 2196
1098 & 3294
1098 & 4392
etc...

That is not all! Any combination of any multiple of 1098 and "odd" multiples of 1098 will also have GCF of 1098. 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 1098.

2196 & 3294
2196 & 5490
4392 & 5490
4392 & 7686
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1098. The lists we created can go on forever.
