question

Find all the factor pairs for 14 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 1. You can use a multiplication fact to find the missing factor.

So, 1 and 14 are a factor pair for 14.

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

So, 2 and 7 are a factor pair for 14.

These equations show all the factor pairs for 14:
