question

Find all the factor pairs for 20 and complete the equations.

key idea

A factor of a number divides the number evenly.

A factor pair for a number is a pair of factors whose product is that number. For example, 2 and 5 are a factor pair for 10 because

solution

Each of the equations is missing a factor. In the first equation, one of the factors is 20. You can use a multiplication fact to find the missing factor.

So, 1 and 20 are a factor pair for 20.

In the second equation, one of the factors is 2. You can use a multiplication fact to find the missing factor.

So, 2 and 10 are a factor pair for 20.

In the third equation, one of the factors is 5. You can use a multiplication fact to find the missing factor.

So, 4 and 5 are a factor pair for 20.

These equations show all the factor pairs for 20:
