What two numbers have a GCF of 1138?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1138.

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 1138. Below is the beginning list of multiples of 1138 (1 through 7) in numerical order.

1. 1138
2. 2276
3. 3414
4. 4552
5. 5690
6. 6828
7. 7966
etc...

Two numbers that have a GCF of 1138 can be 1138 and any other number on the list above. Thus, two numbers that have a GCF of 1138 are:

1138 & 2276
1138 & 3414
1138 & 4552
etc...

That is not all! Any combination of any multiple of 1138 and "odd" multiples of 1138 will also have GCF of 1138. 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 1138.

2276 & 3414
2276 & 5690
4552 & 5690
4552 & 7966
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1138. The lists we created can go on forever.
