what is the least common multiple
The least common multiple is the lowest possible number that has both numbers for a factor. For instance, if you are asked to find the LCM for 4 and 8, the LCM would be 8 because it is divisible by both 4 and 8. If you were given 3 and 4, the LCM would be 12, because it is the lowest possible number that is divisible by both 3 and 4.

L.C.M. or least common multiple means that the number which is mixture of both common and non common numbers.
For example: 56,24,12
56=2*2*2*7
24=2*2*2*3
12=2*2*3
Common factors are: 2*2*2*3
Common factors also called highest common factor or H.C.F.
Non common factor is: 7
Now we multiply both common and non common factors =2*2*2*3*7
The answer is: 168
In maths, everything is done by process.
