What two numbers have a GCF of 1236?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1236.

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 1236. Below is the beginning list of multiples of 1236 (1 through 7) in numerical order.

1. 1236
2. 2472
3. 3708
4. 4944
5. 6180
6. 7416
7. 8652
etc...

Two numbers that have a GCF of 1236 can be 1236 and any other number on the list above. Thus, two numbers that have a GCF of 1236 are:

1236 & 2472
1236 & 3708
1236 & 4944
etc...

That is not all! Any combination of any multiple of 1236 and "odd" multiples of 1236 will also have GCF of 1236. 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 1236.

2472 & 3708
2472 & 6180
4944 & 6180
4944 & 8652
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1236. The lists we created can go on forever.
