What two numbers have a GCF of 1018?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 1018.

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 1018. Below is the beginning list of multiples of 1018 (1 through 7) in numerical order.

1. 1018
2. 2036
3. 3054
4. 4072
5. 5090
6. 6108
7. 7126
etc...

Two numbers that have a GCF of 1018 can be 1018 and any other number on the list above. Thus, two numbers that have a GCF of 1018 are:

1018 & 2036
1018 & 3054
1018 & 4072
etc...

That is not all! Any combination of any multiple of 1018 and "odd" multiples of 1018 will also have GCF of 1018. 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 1018.

2036 & 3054
2036 & 5090
4072 & 5090
4072 & 7126
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 1018. The lists we created can go on forever.
