GCF & Distributive Property

Front

What is the GCF (Greatest Common Factor)?

Back

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

Front

How do you find the GCF of 24 and 56?

Back

List the factors of each number: Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24; Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56. The GCF is 8.

Front

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac. It allows you to multiply a number by a sum by distributing the multiplication.

Front

Use the distributive property to simplify: 5(2 + 3)

Back

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

Front

Find the equivalent expression for: 24 + 30 using GCF.

Back

The GCF of 24 and 30 is 6. So, 24 + 30 = 6(4 + 5).

Front

What is the product of 0.5 and 3.5?

Back

0.5 * 3.5 = 1.75.

Front

If 10 + 20 = 10(1 + __), what is the missing number?

Back

The missing number is 2, because 10 + 20 = 10(1 + 2).

Front

How do you calculate how much farther one person rode than another?

Back

Subtract the shorter distance from the longer distance. For example, Johnny rode 8.1 miles and Alexis rode 4.5 miles. 8.1 - 4.5 = 3.6 miles.

Front

What is the GCF of 12 and 18?

Back

The GCF of 12 and 18 is 6.

Front

Use the distributive property to solve: 3(4 + 5)

Back

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