4. Q: What are the factors of 15?
Q: What is the greatest common factor (GCF) of 15 and 60?
A: 15

5. Greatest Common Factor (GCF) of Monomials
To find the GCF of two or more monomials:
Find the factors of each number
Write all powers of variables as products
Circle the greatest common number
Circle the common variables

6. Directions: Find the GCF of each pair of monomials.
1. 6xy3, 18yz
6xy3: 1, 2, 3, 6, x, y, y, y
18yz: 1, 2, 3, 6, 9, 18, y, z
GCF = 6y

7. Directions: Find the GCF of each pair of monomials.
2. 11a2b, 21ab
11a2b: 1, 11, a, a, b
21ab: 1, 3, 7, 21, a, b
GCF = ab
3. 7gh, 11mp
7gh: 1, 7, g, h
11mp: 1, 11, m, p
GCF = 1

8. Factoring Using the Distributive Property
Directions: Use the distributive property to factor each polynomial.
1. 20z2 + 35z Step 1. Take out GCF
5z(4z) + 5z(7) Step 2. Rewrite each term using the GCF
5z(4z + 7) Step 3. Distributive Property
ALWAYS CHECK USING THE DISTRIBUTIVE PROPERTY

9. Directions: Use the distributive property to factor each polynomial.
2. 27y2 + 18y Step 1. Take out GCF
9y(3y) + 9y(2) Step 2. Rewrite each term using the GCF
9y(3y + 2) Step 3. Distributive Property
3. 15w – 3v
3(5w) – 3(v)
3(5w – v)
4. -4a2b – 8ab2 + 2ab
2ab(-2a) – 2ab(4b) + 2ab(1)
2ab(-2a – 4b + 1)
