45 = 1 ·

45 = 3 ·

45 = ·

Explanation:

Step1: Find factor for 1 pair

To find the missing factor, divide 45 by 1.
$\frac{45}{1}=45$

Step2: Find factor for 3 pair

Divide 45 by 3 to get the missing factor.
$\frac{45}{3}=15$

Step3: Find remaining factor pair

Identify the last unique factor pair of 45.
$5 \times 9 = 45$

Answer:

$45 = 1 \cdot 45$
$45 = 3 \cdot 15$
