What two numbers have a GCF of 357?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 357.

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 357. Below is the beginning list of multiples of 357 (1 through 7) in numerical order.

1. 357
2. 714
3. 1071
4. 1428
5. 1785
6. 2142
7. 2499
etc...

Two numbers that have a GCF of 357 can be 357 and any other number on the list above. Thus, two numbers that have a GCF of 357 are:

357 & 714
357 & 1071
357 & 1428
etc...

That is not all! Any combination of any multiple of 357 and "odd" multiples of 357 will also have GCF of 357. 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 357.

714 & 1071
714 & 1785
1428 & 1785
1428 & 2499
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 357. The lists we created can go on forever.
