Question

find all the factor pairs for 68 and complete the equations. each equation should us different pair of factors.
68 = 1·□
68 = □·□
68 = □·□

Explanation:

Step1: Find factor with 1

Since $1 \times n = n$, the missing factor is 68.
$68 = 1 \times 68$

Step2: Find next smallest factor

2 divides 68 evenly. Calculate $68 \div 2 = 34$.
$68 = 2 \times 34$

Step3: Find remaining factor pair

4 divides 68 evenly. Calculate $68 \div 4 = 17$.
$68 = 4 \times 17$

Answer:

$68 = 1 \cdot 68$
$68 = 2 \cdot 34$
$68 = 4 \cdot 17$
