To find the Least Common Multiple (LCM) of 6, 15, and 21, we first need to find the prime factorization of each number. The prime factorization of 6 is 2 x 3, 15 is 3 x 5, and 21 is 3 x 7. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers: 2 x 3 x 5 x 7 = 210. Therefore, the LCM of 6, 15, and 21 is 210.
