In arithmetic, the least common multiple or LCM of two numbers say a and b, is denoted as LCM (a,b). And the LCM is the smallest or least positive integer that is divisible by both a and b.
LCM of 4 and 6
First write the common multiples of all the two numbers.
Common Multiples of 4 : 4,8,12,16,20,24,28,…..
Common Multiples of 6: 6,12,18,24,30,36,42…..
From the above-given multiples of 4 and 6 is the multiple 12 is the smallest common multiple.
Therefore, LCM. of 4 and 6 is 12.
