In practical terms, it is only necessary to find the LCM of 16 & 18 as 9 is a factor of 18.
Express each number in terms of its prime factors.
16 = 2 x 2 x 2 x 2 = 24
18 = 2 x 3 x 3 = 2 x 32
The LCM is the product of the highest power of each prime factor.
The highest power of 2 is 24 and of 3 is 32.
The LCM is therefore 24 x 32 =16 x 9 = 144
144
LCM(9, 16, 18) = 144
