What two numbers have a GCF of 448?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 448.

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 448. Below is the beginning list of multiples of 448 (1 through 7) in numerical order.

1. 448
2. 896
3. 1344
4. 1792
5. 2240
6. 2688
7. 3136
etc...

Two numbers that have a GCF of 448 can be 448 and any other number on the list above. Thus, two numbers that have a GCF of 448 are:

448 & 896
448 & 1344
448 & 1792
etc...

That is not all! Any combination of any multiple of 448 and "odd" multiples of 448 will also have GCF of 448. 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 448.

896 & 1344
896 & 2240
1792 & 2240
1792 & 3136
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 448. The lists we created can go on forever.
