Q. 94.2( 147 Votes )

Find the smallest

Answer :

we know that the number that will be perfectly divisible by each one of 4, 9, and 10 is their LCM.

The LCM of these numbers is:

LCM of 4, 9, 10 = 2 × 2 × 3 × 3 × 5 =180

Here, prime factor 5 does not have its pair


Therefore, 180 is not a perfect square.


If we multiply 180 with 5, then the number will become a perfect square.

Hence,

The required square number is 180 × 5 = 900
