What is the smallest number by which 8640 is to be divided so that the quotient is a perfect cube?Hence the smallest number by which 135 should be divided to make a perfect cube is 5 . Here,the prime factors 3 is not present as triples. Hence, we divide 192 by 3, so that the obtained number becomes a perfect cube. 192÷3=64=23×23=43 192 ÷ 3 = 64 = 2 3 × 2 3 = 4 3 is a perfect cube.
