Find the greatest common factor of 15x2y3 and -18x3yz.

For this case we have that by definition, the GFC (greatest common factor) of two numbers is given by the greater number that is a factor of both numbers. Then, let:

We decompose into factors:

15: 1,3,5,15

18: 1,2,3,6,9,18

The GFC is 3.

So, we have that the GFC of the expressions is:

10 down (bang1)

5 up

5down (2)

2.5 up

2.5 down (3)

1.25 up

1.25 down (4)

now add them up : )

hoped i lol
