Question 59

By which least number should 1568 be divided so that the resultant number is a perfect square?

Solution

First multiply the given number with the least number given in the options i.e 2 and check whether it is a perfect square or not. 

$$\Rightarrow$$ 1568 / 2 = 784

784 is a perfect square (square of 28). So, the least number that should divide 1568 to get the resultant as a perfect square is '2'

Hence, option A is the correct answer.
