Question

By which smallest number must the following numbers be divided, so that the quotient is perfect cube? ​

Answer 1

To make the quotient a perfect cube we divide it by 5, which gives 1728 as quotient and we know that 1728 is a perfect cube. ∴5 is the required smallest number. Since 1600 is not a perfect cube. ∴ 25 is the required smallest number.
