To find the least common multiple (LCM) of 21, 42, and 56, first find the prime factorization of each number.
21 = 3 x 7 42 = 2 x 3 x 7 56 = 2 x 2 x 2 x 7
Then, identify the highest power of each prime factor that appears in any of the factorizations.
LCM = 2^3 x 3 x 7 = 56 x 3 x 7 = 1176
Therefore, the least common multiple of 21, 42, and 56 is 1176.
