Answer:
In order to find the least number, we need to do the LCM of 16,18 and 45.
Prime factorization of 16 = 2^4
Prime factorization of 18 = 2 * 3 * 3
Prime factorization of 45 = 3 * 3 * 5
LCM(16,18,45) = 2^4 * 3^2 * 5
= 720.
As we can see here, 5 is not in pair. So, we need to multiply 720 by 5 to make it a perfect square.
= > 720 * 5
= > 3600.
Therefore, the least perfect square number = 3600.
Hope this helps!
