Least Common Multiple (LCM) Calculator Explanation


LCM stands for Least Common Multiple (LCM). The least common multiple (LCM) of two numbers is the smallest number that both numbers can divide by. Furthermore, it can be calculated using two or more numbers. To determine the LCM of a given collection of numbers, there are various techniques. Using the prime factorization of each number and then calculating the product of the highest powers of the common prime factors is one of the quickest ways to determine the LCM of two numbers.

What is Least Common Multiple (LCM)?

LCM or the lowest common multiple are two terms used to refer to the least common multiple in mathematics. Among all possible multiples of the provided numbers, the least frequent multiple of two or more numbers is the one with the smallest value.  

How to Find LCM?

The LCM of a set of numbers can be calculated in a variety of different ways. There are three approaches to determining the least common multiple of two numbers. The name of the techniques are given below.
=> Listing Method - LCM
=> Prime Factorization - LCM
=> Division Method -LCM

The formula for calculating Least Common Multiple (LCM) is

LCM(a,b) =
|a . b| / GCD(a,b)

How to solve Least Common Multiple - LCM with a calculator?

LCM example 1:

Number: (34,56)

LCM(a,b) =
|34 x 56| / GCD(34,56)
= 952

LCM example 2:

Number: (2,4,6,8)

LCM(a,b) =
|2 x 4 x 6 x 8| / GCD(2,4,6,8)
= 24

LCM example 3:

Number: (3,5,7)

LCM(a,b) =
|3 x 5 x 7| / GCD(3,5,7)
= 105
