Explanation:

L.C.M. of 21, 36, 66 = 2772.

Now, 2772 = 2 x 2 x 3 x 3 x 7 x 11

To make it a perfect square, it must be multiplied by 7 x 11.

So, required number = 22 x 32 x 72 x 112 = 213444

= (1)2 + (2a)2 – 2 x 1 x 2a + 3a

   = (1 – 2a)2 + 3a

   = (1 – 2a) + 3a

   = (1 + a)

   = (1 + 0.1039)

   = 1.1039
