What two numbers have a GCF of 98?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 98.

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 98. Below is the beginning list of multiples of 98 (1 through 7) in numerical order.

1. 98
2. 196
3. 294
4. 392
5. 490
6. 588
7. 686
etc...

Two numbers that have a GCF of 98 can be 98 and any other number on the list above. Thus, two numbers that have a GCF of 98 are:

98 & 196
98 & 294
98 & 392
etc...

That is not all! Any combination of any multiple of 98 and "odd" multiples of 98 will also have GCF of 98. 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 98.

196 & 294
196 & 490
392 & 490
392 & 686
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 98. The lists we created can go on forever.
