The least common multiple (LCM) is the smallest positive integer that is divisible by both of the given numbers, 12 and 18. To find the LCM, we need to find the smallest number that is a multiple of both 12 and 18. Option A, 6, is incorrect because it is a multiple of neither 12 nor 18. Option B, 12, is incorrect because it is not a multiple of 18. Option C, 18, is incorrect because it is not a multiple of 12. Option D, 36, is the correct answer as it is the smallest number that is divisible by both 12 and 18. Therefore, the least common multiple of 12 and 18 is 36.
