GCF,LCM, Distributive Property

Front

What is the Greatest Common Factor (GCF)?

Back

The GCF is the largest number that divides two or more numbers without leaving a remainder.

Front

How do you find the Least Common Multiple (LCM) of two numbers?

Back

To find the LCM, list the multiples of each number and identify the smallest multiple they have in common.

Front

Calculate the GCF of 12 and 16.

Back

The GCF of 12 and 16 is 4.

Front

Calculate the LCM of 4 and 5.

Back

The LCM of 4 and 5 is 20.

Front

What is the Distributive Property?

Back

The Distributive Property states that a(b + c) = ab + ac.

Front

Use the Distributive Property: 5(2 + 3).

Back

5(2 + 3) = 5*2 + 5*3 = 10 + 15 = 25.

Front

Rewrite using GCF: 18 + 24.

Back

The GCF is 6, so 18 + 24 = 6(3 + 4).

Front

Rewrite using GCF: 30 + 45.

Back

The GCF is 15, so 30 + 45 = 15(2 + 3).

Front

What is the LCM of 8 and 12?

Back

The LCM of 8 and 12 is 24.

Front

Calculate the GCF of 20 and 30.

Back

The GCF of 20 and 30 is 10.
