Answer: The correct option is (C) 72.
Step-by-step explanation: We are given to select the correct number that is the least common multiple of 24 and 36.
The Least Common Multiple (LCM) of some numbers smallest multiple such that it is divisible by all the numbers.
So, the LCM of 24 and 36 is the smallest number which is divisible by both 24 and 36.
We have

Therefore, the LCM of 24 and 36 is given by

Thus, the least common multiple of 24 nad 36 is 72.
Option (C) is correct.
