Correct Answer - Option 1 : 2
Calculation:
Prime factors of 1568 = 2 × 2 × 2 × 2 × 2 × 7 × 7
Perfect square number pairs = (2 × 2) × (2 × 2) × 2 × (7 × 7)
Here 2 doesn't have pair
So, 2 should be multiplied by 1568 to make it a perfect square
∴ The smallest number to be multiplied with 1568 to make it a perfect square is 2
In these type of questions, firstly we have to make prime factors then make perfect square numbers.
