What two numbers have a GCF of 1203?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1203.

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 1203. Below is the beginning list of multiples of 1203 (1 through 7) in numerical order.

1. 1203
2. 2406
3. 3609
4. 4812
5. 6015
6. 7218
7. 8421
etc...

Two numbers that have a GCF of 1203 can be 1203 and any other number on the list above. Thus, two numbers that have a GCF of 1203 are:

1203 & 2406
1203 & 3609
1203 & 4812
etc...

That is not all! Any combination of any multiple of 1203 and "odd" multiples of 1203 will also have GCF of 1203. 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 1203.

2406 & 3609
2406 & 6015
4812 & 6015
4812 & 8421
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1203. The lists we created can go on forever.
