The LCM is 441.

For the values: 21, 9 the LCM is: 63

lcm(49, 63, 21) = 441 49 = 7^2 63 = 3^2 x 7 21 = 3 x 7 lcm = 3^2 x 7^2 = 441

21 is a factor of 63 (21 * 3 = 63).71 is a prime number.Since 71 has no common factors with 63, they must be multiplied together to find their least common multiple.Thus, the least common multiple (LCM) of 21, 63 and 71 is 63 * 71 = 4473.

The Least Common Multiple (LCM) for 21 3 9 is 63.
