Answer
$120 = 2 \cdot 2 \cdot 2 \cdot 3 \cdot 5$
Work Step by Step
The number is even so it is divisible by 2. Factor out 2 to obtain:
$120= 2 \cdot 60$
60 is even, so factor out 2 to obtain:
$120 = 2 \cdot 2 \cdot 30$
30 is even, so factor out 2 to obtain:
$120 = 2 \cdot 2 \cdot 2 \cdot 15$
15 is divisible by 3 so factor out 3 to obtain:
$120 = 2 \cdot 2 \cdot 2 \cdot 3 \cdot 5$
