To find the LCM of a set of numbers, you first need to work out their prime factors:
2=2
4=2x2
7=7
14=2x7
The next step is to identify any common factors. Three numbers have a 2, so two of these can be discarded. Also, two numbers have a 7, so one of these can be discarded. This leaves us with 2, 2 and 7. To find the LCM we simply multiply these numbers together:
2x2x7 = 28
Thus the LCM of 2, 4, 7 and 14 is 28.

The Least Common Multiple (LCM) for 2 7 is 14.
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
182 Prime Factorization of: 14 =...2 * 7 26 =...2 .....* 13 =========== LCM= 2 * 7 * 13 = 182
The LCM is: 28
The Least Common Multiple (LCM) for 4 7 2 is 28.
