Solution:
53240 = 2 × 2 ×2 ×11 ×11× 11×5
The prime factor does not appear in a group of three. So, 53240 is not a perfect cube
In the factorisation 5 appears only one time If we divide the number by 5. then the prime factonsation of the quotient will not contain 5.
53240 + 5 = 2×2×2×11×
Hence the smallest number by which 53240 should be divided to make it a perfect cube is 5
The perfect cube in that case is = 10648
