Question

find all the factor pairs for 84 and complete the equations.
84 = \square \cdot 84
84 = 2 \cdot \square
84 = 3 \cdot \square
84 = 4 \cdot \square
84 = 6 \cdot \square
84 = \square \cdot 12

Explanation:

Step1: Solve for first missing factor

To find the factor, divide 84 by 84.
$\frac{84}{84}=1$

Step2: Solve for second missing factor

Divide 84 by 2 to find the pair.
$\frac{84}{2}=42$

Step3: Solve for third missing factor

Divide 84 by 3 to find the pair.
$\frac{84}{3}=28$

Step4: Solve for fourth missing factor

Divide 84 by 4 to find the pair.
$\frac{84}{4}=21$

Step5: Solve for fifth missing factor

Divide 84 by 6 to find the pair.
$\frac{84}{6}=14$

Step6: Solve for sixth missing factor

Divide 84 by 12 to find the pair.
$\frac{84}{12}=7$

Answer:

$84 = 1 \cdot 84$
$84 = 2 \cdot 42$
$84 = 3 \cdot 28$
$84 = 4 \cdot 21$
$84 = 6 \cdot 14$
$84 = 7 \cdot 12$
