Did you mean GCF? If so, the greatest common factor is 9

Explanation:

The greatest common factor is the largest number that all or the numbers you are given have as a factor. It is easiest to find this by listing out the factors of all of the numbers that you have. Factors are the numbers that when multiplied equal the original number.

We'll start with 18:
1, 2, 3, 6, 9, and 18 are all factors of 18

Now for 27:
1, 3, 9, and 27 are 27's factors.

To find the GCF, we want to take the largest of the factors that the two numbers share. In this case, it would be 9.

I hope this helped!
