# Least Common Multiple Calculator

## LCM of two Numbers

Note
• Enter the values of the two numbers whose LCM need to be calculated
• Click on the calculate button.
Formula used
$LCM=\frac{a \times b}{Gcf(a,b)}$

### LCM Calculator

Example of Few questions where you can use this formula
• Find the LCM of 25 and 625
• Find the LCM of 14 and 700

## What is Least Common Multiple

• Least Common Multiple or LCM of two numbers a nd b is the smallest postive integer which is evenly divisible by the numbers a and b. It is called lowest common multiple or Lowest common divisible.
• LCM can be obtained using prime fractorization technique. Here we find the LCM using the below Formula
LCM (a,b) = \frac { HCF(a,b)}{a \times b}

## How the LCM calculator works

• First we need to input the two positive integers whose LCM is required to be calculated
• Now HCF of a and b is calculated using Euclid Division Lemma
• Now the LCM is obtained using the formula
LCM (a,b) = \frac { HCF(a,b)}{a \times b}

## LCM of more than two Numbers

Note
• Enter the values of the more than 2 numbers seperated by commas whose gcf need to be calculated Example 2,3,4
• Click on the calculate button.

Formula used
$LCM(a,b,c,d) = LCM(LCM(LCM(a,b),c),d)$

### LCM Calculator

Example of Few questions where you can use this formula
• Find the LCM of 12,8,16,32
• Find the LCM of 3,8,18,36

## How the LCM calculator works

• First we need to input the positive integers whose LCM is required to be calculated
• Now first we calculate the LCM of first two values using the formula
LCM (a,b) = \frac { HCF(a,b)}{a \times b}
• Now the LCM obtained and third number is taken and LCM is again obtained using the same technique.
• We keep doing until all numbers are absorbed, final LCM is obtained
