LCM using Division Method
First, we need to write all the numbers in a horizontal line separated by commas. Then, we divide all the given numbers by the smallest prime number. Then, we write the quotient and undivided numbers in a new line below the previous line.
We repeat this procedure until we come to the stage where no prime factor is common. The, we find the product of all divisors and the resultant number we get is the LCM.
Example: Find LCM of 6, 8, 5, 4, 3 by Division method.
Solution:
LCM of 6, 8, 5, 4, 3 can be calculated as follow:
Hence the LCM(6, 8, 5, 4, 3) = 120

LCM Formula
LCM Formula: LCM stands for Least Common Multiple. LCM of two numbers say a and b is defined as the smallest positive integer divisible by both the numbers a and b. Hence, the LCM is the smallest common multiple of two or more numbers. It is also called lowest common multiple, or smallest common multiple.
In this article, we will discuss LCM, Formulas to calculate LCM, and different methods used to find the LCM of two or more numbers.
