Least Common Multiple(LCM) is a method to find the smallest common multiple between any two or more numbers. A common multiple is a number which is a multiple of two or more numbers. LCM denotes the least common factor or multiple of any two or more given integers.
LCM of 2 and 4
To find the LCM of 2 and 4, let us write the multiples of both the numbers first.
Multiples of 2 = 2,4,6,8,10,12…
Multiples of 4 = 4,8,12,16,20,24..
Hence, the smallest common multiple here 4.
So, LCM (2,4) = 4
Hence, LCM of 2 and 4 is 4
