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
The LCM is: 28
lcm(2, 7) = 14 5th multiple is 5 x 14 = 70
The LCM is: 56
The LCM is: 6
2
42
10
78
60
Since 4 is a multiple of 2, it is automatically the LCM.
Factor 6 and you get 2*3. Therefore, 6 is divisible by 6, 2, and 3 Therefore, the LCM of all three is 6
X = 10II = 2and VII = 7
