find the gcf of 18j+27

To find the greatest common factor (GCF) of 18j + 27, we need to factor out the common factors of 18 and 27.

First, let's write 18j + 27 as a product of its prime factors:
18j + 27 = 3 * 6j + 3 * 9
= 3 * (6j + 9)
= 3 * 3 * (2j + 3)

Now, we can see that the GCF of 18j + 27 is 3.
