What two numbers have a GCF of 281?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 281.

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 281. Below is the beginning list of multiples of 281 (1 through 7) in numerical order.

1. 281
2. 562
3. 843
4. 1124
5. 1405
6. 1686
7. 1967
etc...

Two numbers that have a GCF of 281 can be 281 and any other number on the list above. Thus, two numbers that have a GCF of 281 are:

281 & 562
281 & 843
281 & 1124
etc...

That is not all! Any combination of any multiple of 281 and "odd" multiples of 281 will also have GCF of 281. 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 281.

562 & 843
562 & 1405
1124 & 1405
1124 & 1967
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 281. The lists we created can go on forever.
