The LCM of 16, 45, 135 and 144 is:

Correct option is C

Given:

Numbers = 16, 45, 135, 144

Solution:

Prime factorization:

16 = $$2^4$$​​

45 = $$3^2 \times 5$$​​

135 = $$3^3 \times 5$$​​

144 = $$2^4 \times 3^2$$​​

So, 

LCM = $$2^4 \times 3^3 \times 5$$​​

= $$16 \times 27 \times 5$$​​

= 2160
