How do you you find the gcf of monomials?

Answer 1

Let's try one.

30x2y3z4 + 42x4y5z2

Do the numbers first.

Example: 30 and 42

Factor them.

2 x 3 x 5 = 30

2 x 3 x 7 = 42

Select the common factors.

2 x 3 = 6

For the variables, select the lowest exponent.

The GCF of the above expression is 6x2y3z2
