To find the least common multiple (LCM) of 6, 15, and 20, we first need to find the prime factorization of each number. The prime factorization of 6 is 2 x 3, the prime factorization of 15 is 3 x 5, and the prime factorization of 20 is 2^2 x 5. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers: 2^2 x 3 x 5 = 60. Therefore, the LCM of 6, 15, and 20 is 60.
