Answer
$135 = 5 \cdot 3 \cdot 3 \cdot 3$
Work Step by Step
The number ends with 5, so it is divisible by 5. Factor out 5 to obtain:
$135= 5 \cdot 27 $
27 is divisible by 3, so factor out 3 to obtain:
$135 = 5 \cdot 3 \cdot 9$
9 is divisible by 3, so factor out 3 to obtain:
$135 = 5 \cdot 3 \cdot 3 \cdot 3$
