Answer: 36

Step-by-step explanation: A common multiple is a number that is a multiple of at least two numbers.

To find out the least common multiple of 12 and 18, we can use prime factorization for each number.

12 = 2 × 2 × 3

18 = 2 × 3 × 3

Least Common Multiple = 2 × 2 × 3 × 3 = 36

LCM of 12 and 18 is 36.
