What two numbers have a GCF of 402?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 402.

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 402. Below is the beginning list of multiples of 402 (1 through 7) in numerical order.

1. 402
2. 804
3. 1206
4. 1608
5. 2010
6. 2412
7. 2814
etc...

Two numbers that have a GCF of 402 can be 402 and any other number on the list above. Thus, two numbers that have a GCF of 402 are:

402 & 804
402 & 1206
402 & 1608
etc...

That is not all! Any combination of any multiple of 402 and "odd" multiples of 402 will also have GCF of 402. 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 402.

804 & 1206
804 & 2010
1608 & 2010
1608 & 2814
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 402. The lists we created can go on forever.
