What is the smallest number by which 2880 must be divided in order to make it into a perfect square ?
(a) 3 (b) 4 (c) 5 (d) 6

• 2880/3=960 is not a perfect square
  2880/4=720 is not a perfect square
  2880/5=576 which is perfect square of 24
  hence the answer is option c)5

• the prime factor of 2880 is 2^6*3^2*5
  there is an even no of power of each except 5 so when we divide the no by 5 we get 2^6*3^2=(2^3*3)^2
  which is nothing but 24^2

• LCM of 2880=2^6*3^2*5
  since 5 is not paired so 5 is divided to make perfect square
  OPTION C

• 2880/5=576
  576 is the perfect square of 24
  (24)^2=576
