What two numbers have a GCF of 238?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 238.

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 238. Below is the beginning list of multiples of 238 (1 through 7) in numerical order.

1. 238
2. 476
3. 714
4. 952
5. 1190
6. 1428
7. 1666
etc...

Two numbers that have a GCF of 238 can be 238 and any other number on the list above. Thus, two numbers that have a GCF of 238 are:

238 & 476
238 & 714
238 & 952
etc...

That is not all! Any combination of any multiple of 238 and "odd" multiples of 238 will also have GCF of 238. 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 238.

476 & 714
476 & 1190
952 & 1190
952 & 1666
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 238. The lists we created can go on forever.
