Heya user,

2340 = 2 * 2 * 3 * 3 * 5 * 13;

For making it a perfect cube, we need pairs of 3 prime factors --->

Which is ---> 2 * 2 * 2 * 3 * 3 * 3 * 5 * 5 * 5 * 13 * 13 * 13 = 2
³ * 3³ * 5³ * 13³
Which is ---> ( 2² * 3² * 5 * 13 ) * ( 2 * 3 * 5² * 13²)
Which is -----> 2340 * 25350

Hence, the least no. we need to multiply with 2340 to get a perfect cube is ======> 25350
