Correct Answer - Option 1 : 5
Given:
The number = 68600
Calculation:
⇒ 68600 = 2 × (34300)
⇒ 34300 = 2 × (17150)
⇒ 17150 = 2 × (8575)
⇒ 8575 = 5 × (1715)
⇒ 1715 = 5 × (343)
⇒ 343 = 7 × (49)
⇒ 49 = 7 × 7
⇒ 68600 = (2 × 2 × 2) × (5 × 5) × (7 × 7 × 7)
⇒ In expansion of the number we can see if we multiply by 5 then given number would be a perfect cube.
∴ The required result will be 5.
