Correct Answer: One
Explanation
To find the LCM (Least Common Multiple) of several numbers, you can list the multiples of each number and then find the smallest multiple that is common to all of the numbers.
As we see 36 is the least common multiple of the numbers 12, 18, 6 and 36, so the LCM of 12, 18, 6, 36 is 36.
