Find the smallest square number that is divisible by each of the numbers 4, 9 and 10
Solution:
The number that will be perfectly divisible by each of the numbers 4, 9 and 10 will be their LCM.
LCM of 4, 9, 10
= 2 × 2 × 3 × 3 × 5
= 180
Here, the prime factor 5 does not have a pair. Therefore 180 is multiplied by 5 then the number obtained is a perfect square.
Thus, 180 × 5 = 900
So, 900 is the smallest square that is divisible by 4, 9, and 10
