What two numbers have a GCF of 104?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 104.

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 104. Below is the beginning list of multiples of 104 (1 through 7) in numerical order.

1. 104
2. 208
3. 312
4. 416
5. 520
6. 624
7. 728
etc...

Two numbers that have a GCF of 104 can be 104 and any other number on the list above. Thus, two numbers that have a GCF of 104 are:

104 & 208
104 & 312
104 & 416
etc...

That is not all! Any combination of any multiple of 104 and "odd" multiples of 104 will also have GCF of 104. 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 104.

208 & 312
208 & 520
416 & 520
416 & 728
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 104. The lists we created can go on forever.
