To find the Least Common Multiple (LCM) of 6, 9, and 36, we first need to factor each number into its prime factors. The prime factorization of 6 is 2 x 3, the prime factorization of 9 is 3 x 3, and the prime factorization of 36 is 2 x 2 x 3 x 3. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers: 2^2 x 3^2 = 36. Therefore, the LCM of 6, 9, and 36 is 36.
