Question

find the smallest number by which 1323 must be multiplied so that the product is a perfect cube​

Answer 1

First by finding lcm

$\underline{3}| \underline{1323} \\ \underline{3} |\underline{441} \\ \underline{7} |\underline{147} \\\underline{7} | \underline{21} \\ \underline{3} |\underline{3} \\ \underline{ \: \: \: } |\underline{1}$

Now 3 must be multiply again so we will get 3969 which will be perfect cube of 63.
