- Find the smallest number by which 5400 should be multiplied so that the product is a perfect cube. The following steps are involved in solving the above problem. Arrange them in sequential order. (A) ⇒ 5400=23 × 33 × 52 (B) On prime factorization of 5400 , we get 5400= 2 × 2 × 2 × 5 × 5 × 3 × 3 × 3. (C) ∴ 5400 must be multiplied by 5 so that the product is a perfect cube. (D) In the prime factorization of 5400 , we observe that 5 has not appeared n times, where n is a multiple of 3 .
