The LCM is 42
The LCM is: 84
The multiples of 7 are 7, 14, 21, 28, 35, 42, etc.The multiples of 14 are 14, 28, 42, etc.The multiples of 21 are 21, 42, etc.The least common multiple (LCM) of 7, 14, and 21 is 42
42
The Least Common Multiple (LCM) of 6, 7, and 21 is 42.
2 x 7 = 14 3 x 7 = 21 2 x 3 x 7 = 42, the LCM
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.
2 x 7 = 14 3 x 7 = 21 2 x 3 x 7 = 42, the LCM
The least common multiple of the numbers 21, 14 and 7 is 42.
It's 126. -- the 6th multiple of 21 -- the 9th multiple of 14 -- the 14th multiple of 9
Since 14 is a multiple of 7, it is automatically the LCM.
It is: 294 which is the same as its LCM
