Number which divides 2, 4, 6 will be in table of these numbers
So, it will be a multiple.
Since it divides all these numbers, it will be a common multiple
Multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, ….
Multiples of 4 are 4, 8, 12, 16, 20, 24, 28, 32 ….
Multiples of 6 are 6, 12, 18, 24, 30, 36, …
So, common multiples are 12, 24, ..
Here, we need to find the smallest number
So, Smallest number = 12
And this is the number which when divided by 2, 4, 6 gives remainder 0
And it is also the LCM – Least Common multiple
So, LCM = Number which gives remainder 0 when dividing by 2, 4, 6
