The least common multiple of 2 , 3 , 7 = 42
Let's look at the 2 and 7 times tables... 2, 4, 6, 8, 10, 12, 14, 16... 7, 14, 21, 28... 14 is the first number to be in both times tables. Therefore, the lowest common multiple (LCM) of 2 and 7 is 14
multiple of 7 = 7,14,21,28,35,42,49,56,63,70,77....... multiple of 8 = 8,16,24,32,40,48,56,64,72,80,88.......... so the lcm of 7&8 is 56.
The LCM is: 35
The Least Common Multiple (LCM) of 6 and 7 is 42.
