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 GCF of two numbers?

Back

List the factors of each number and identify the largest factor they have in common.

What is the distributive property in mathematics?

Back

The distributive property states that a(b + c) = ab + ac, meaning you can distribute a number across a sum.

Front

How can you use the distributive property to simplify expressions?

Back

By breaking down a sum into products, making calculations easier.

What is an example of using the GCF in real life?

Back

Dividing items into equal groups, like cookies into containers.

Front

What does it mean to rewrite an expression using the distributive property?

Back

It means to express the sum as a product of a common factor and a simplified sum.
