LCM Calculator

Aim of LCM Caluclatoe with variables to provide valueable online experience to solve homework and routine assignment work. This is Educational purpose tool for students and Education institutes. Quick and Accurate LCM Results will saves your time and energy.

What LCM Calculator with Variables is?

The Least Common Multiple is also known as Least Common Divisor or Lowest Common Multiple. Suppose there is two integers 3 and 4, now we have to know about a lowest number which is properly divided by these two numbers. So here 12 is Least Common Multiple / Divisor of 3 and 4, because 12 is divisible by 3 and 4 both.

So, I can say that LCM is smallest number which is divisible by every integer in given comma separated input series.

LCM Calculator with variables have three calculation methods:

  1. How to find LCM using Factorization Method?
  2. How to find LCM using Division Method?
  3. How to find LCM List of Multiple Method?

How to find LCM using Factorization Method?

In this method, we need to follow some steps to get LCM / LCD Results, here is steps listed:

  • List out Prime Factors of Each Given Number (Collect all prime numbers as often each occurrence)
  • Multiple all collected List of prime numbers to determine LCM.

Note: Same procedure is used for two variables as well as more than two variables, to find prime factors and multiply them together.

Find LCM( 9 , 12 ) by Prime Factorization – Example

Division of 9 with prime numbers

Prime Factors of 9 are 3 × 3

Division of 12 with prime numbers

Prime Factors of 12 are 2 × 2 × 3

Common prime factor of 9 and 12

Here is collective prime factors list is 3 × 3 × 2 × 2 and LCM of 9 and 12 is 36

How to find LCM using Division Method?

To calculate Least Common Multiple using division method given set of integers set in a cake/ladder way to get one’s at bottom as remainder. at Left side you will get Prime Integers to determine LCM by multiply. Let do an example to learn more about this method theoretically.

Find LCM( 24 , 30 ) by Division Method – Example

Here division table of 24 by prime integers, must need to start from as much as lower number can divide target number.

224 , 30
212 , 15
26 , 15
33 , 15
51 , 5
1, 1
Division of 24

Here we get List of Prime Integers 2, 2, 2, 3, 5 to find out LCM of 24 and 30, let’s do another step to multiply these values together.

LCM(24, 30) = 2 × 2 × 2 × 3 × 5 = 120 is Least Common Multiple Answer.

How to find LCM List of Multiple Method?

In this method, LCM calculator with variables works in a way to expand each variable’s multiples to get a very common smaller integer in every list. Suppose if we have 3 variables and expand their multiple’s list and get lowest X as common value in three lists

Let’s jump into a simple example to understand that concept.

Suppose Find LCM of 18 and 24 using List of Multiples method

Multiples of 18 are (18 , 36, 54, 72, 90, 108)
Multiples of 24 are (24 , 48, 72, 96, 120)

Here You can see 72 is prominent and its also most smaller common multiple of 18 and 24 multiples list. So, I can write 72 is LCM of 18 and 24. Its very simple and easy to understand this concept.

Common Terms Used in LCM Calculator with Variables

Here is some common Or Same terms and abbreviated words list for LCM, let me list down

  • HCF stands for Highest Common Factor
  • GCF stands for Greatest Common Factor (GCF Calculator)
  • GCD stands for Greatest Common Divisor
  • HCM stands for Highest Common Measure
  • GCM stands for Greatest Common Measure
  • HCD stands for Highest Common Divisor

Formulas Used in LCM Calculator With Variables

Here is some Least Common Multiple from different variables calculation formulas are common. Usually formula needs two variables minimum but for multiple variables we need to use formula recursively. It simple means use answer of each pair to make new pair with next variable until last one.

A set ok very useful, concise and common formulas, you might already know these all.

Commonly user Formulas for LCM are following:

LCM via Greatest Common Factor: LCM(x,y) = x×y / GCF(x,y)

Distributive LCM: LCM(ax,ay,az) = a LCM(x,y,z)

Associative LCM: LCM(x,y) = LCM(y,x)

Role of Venn Diagrams to find LCM?

Venn Diagrams is visible here as Overlapping circles graph visuals. Basically overlapped region show common data in different data sets. These circular regions took from multiples of two or more variables as dataset. Shaded intersection of data sets is LCM common area. Let me show you as an example image.

Here in this Example suppose A and B two Different data sets of multiples, and C is region of common elements, also we demonstrate for prime factors lists as well.
