Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 2640.
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 2640. Below is the beginning list of multiples of 2640 (1 through 7) in numerical order.
1. 2640
2. 5280
3. 7920
4. 10560
5. 13200
6. 15840
7. 18480
etc...
Two numbers that have a GCF of 2640 can be 2640 and any other number on the list above. Thus, two numbers that have a GCF of 2640 are:
2640 & 5280
2640 & 7920
2640 & 10560
etc...
That is not all! Any combination of any multiple of 2640 and "odd" multiples of 2640 will also have GCF of 2640. 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 2640.
5280 & 7920
5280 & 13200
10560 & 13200
10560 & 18480
etc...
Like we stated above, there are infinite combinations of two numbers whose GCF is 2640. The lists we created can go on forever.
