Front

What is the GCF of two numbers?

Back

The GCF (Greatest Common Factor) is the largest number that divides two or more numbers without leaving a remainder.

Front

How do you find the 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

What is the Distributive Property?

Back

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

Front

Give an example of using the Distributive Property: 3(4 + 5)

Back

3(4 + 5) = 3*4 + 3*5 = 12 + 15 = 27.

Front

List the first 5 multiples of 5.

Back

5, 10, 15, 20, 25.

Front

What is the relationship between GCF and LCM?

Back

The product of the GCF and LCM of two numbers is equal to the product of the numbers themselves.
