Answer 1

2 | 5400

2 | 2700

2 | 1350

3 | 675

3 | 225

3 | 75

5 | 25

5 | 5

5400 = 2 × 2 × 2 × 3 × 3 ×3 × 5 × 5

= (2 × 2 × 2) (3× 3 × 3) × 5 × 5

Triplet of 2 and 3 is completed but Triplet of 5 is not completed, so on multiplying the given number by 5 we get a perfect cube.

Required number = 5
