To find the Least Common Multiple (LCM) of 7, 14, and 21, we first need to factorize each number. The prime factors of 7 are 7, of 14 are 2 x 7, and of 21 are 3 x 7. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers. Therefore, LCM(7, 14, 21) = 2 x 3 x 7 = 42.
