Question

Find the smallest number by which 20250 must be divided to make it a perfect cube

Answer 1

Divide the number by 2 and the number will be 10125 which is perfect cube of 15

Answer 2

20250 = 2x3x3x3x3x5x5x5

As 3 and 5 (underlined) are making a pair of 3.

So, the numbers left are 2 and 3

Therefore, 20250 must be divided by 6 (2x3) to make it a perfect cube

20250 ÷ 6 = 3375 which is a cube of 15.
