The Least Common Multiple (LCM) of 6, 7, and 21 is 42.
14
The LCM is 105.
The LCM of 7 21 35 is 105
The LCM is 210.
Note that 21 x 2 = 42, so we really only need to look at 35 and 42. So 7 x 5 = 35, and 7 x 6 = 42. There is a common factor of 7. So we have 7 x 5 x 6 = 210 is the LCM.
LCM of 4 7 12 21 is 84
The LCM is 42.
42
the lcm of 3 and 7 is 21 and the lcm of 7 and 21 is 21, so the lcm of 3, 7 and 21 is the lcm of 21 and 21 which is 21.
LCM(6, 7, 21) = 42
