Step 1.1.1

Factor out the GCF of $3 x$ from the expression $9 x^{3}$ .

$3 x (3 x^{2}) + 9 x^{2} - 18 x + 6 x^{5} + 24 x^{4} + 24 x^{3}$

Step 1.1.2

Factor out the GCF of $3 x$ from the expression $9 x^{2}$ .

$3 x (3 x^{2}) + 3 x (3 x) - 18 x + 6 x^{5} + 24 x^{4} + 24 x^{3}$

Step 1.1.3

Factor out the GCF of $3 x$ from the expression $- 18 x$ .

$3 x (3 x^{2}) + 3 x (3 x) + 3 x (- 6) + 6 x^{5} + 24 x^{4} + 24 x^{3}$

Step 1.1.4

Factor out the GCF of $3 x$ from the expression $6 x^{5}$ .

$3 x (3 x^{2}) + 3 x (3 x) + 3 x (- 6) + 3 x (2 x^{4}) + 24 x^{4} + 24 x^{3}$

Step 1.1.5

Factor out the GCF of $3 x$ from the expression $24 x^{4}$ .

$3 x (3 x^{2}) + 3 x (3 x) + 3 x (- 6) + 3 x (2 x^{4}) + 3 x (8 x^{3}) + 24 x^{3}$

Step 1.1.6

Factor out the GCF of $3 x$ from the expression $24 x^{3}$ .

$3 x (3 x^{2}) + 3 x (3 x) + 3 x (- 6) + 3 x (2 x^{4}) + 3 x (8 x^{3}) + 3 x (8 x^{2})$

Step 1.2

Since all the terms share a common factor of $3 x$ , it can be factored out of each term.

$3 x (3 x^{2} + 3 x - 6 + 2 x^{4} + 8 x^{3} + 8 x^{2})$

Step 2

The greatest common factor $GCF$ is the term in front of the factored expression.
