What two numbers have a GCF of 1242?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1242.

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 1242. Below is the beginning list of multiples of 1242 (1 through 7) in numerical order.

1. 1242
2. 2484
3. 3726
4. 4968
5. 6210
6. 7452
7. 8694
etc...

Two numbers that have a GCF of 1242 can be 1242 and any other number on the list above. Thus, two numbers that have a GCF of 1242 are:

1242 & 2484
1242 & 3726
1242 & 4968
etc...

That is not all! Any combination of any multiple of 1242 and "odd" multiples of 1242 will also have GCF of 1242. 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 1242.

2484 & 3726
2484 & 6210
4968 & 6210
4968 & 8694
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1242. The lists we created can go on forever.
