The LCM of 14 and 21 is 42.
The LCM is 112.
The LCM is 252.
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.
LCM(21, 28, 42) = 84
