How do I Calculate LCM?

LCM stands for the least common Multiple. It is simply the lowest possible number which is divisible by a set of numbers for which you are calculating LCM, hence also known as the Least common divisor. There are several methods to calculate LCM and also it can be calculated for two or more sets of numbers. Provided here is the quickest way of all for finding the LCM for 3 numbers. LCM is most commonly required while performing the long and complicated calculations for addition and subtraction with the fractions to make the value of the denominator common for all fractions.

How to Find LCM of 3 Numbers? 

LCM of 3 numbers can be found using the prime factorization Method. To find LCM of 3 Numbers here is the steps using the prime factorization Method.

  1. Find out the Prime Factors for the set of numbers you wish to calculate LCM for.
  2. You can find the prime factor of a number by using the multiplying method 
  3. Now, write the Number in exponent form. 
  4. Find the product of prime numbers that has the highest power of each Number.
  5. Finally, the result will be the LCM of a chosen set of numbers.

Solved Example: LCM of Three Numbers by Prime Factorization


Find the LCM of 24, 16 and 32 by the prime factorization method.


First, let's find out the Prime factorization of 24, 16 and 32: 

24= 3×2×2×2, 

16= 2×2×2×2 and 32= 2×2×2×2×2.

Prime factors in their exponent form of 24 = 2(3) × 3(1), 

16 = 2(4) and 32 = 2(5).

The product of those factors of the highest powers is 2(5) × 3(1) = 2×2×2×2×2×3=96.

Hence, LCM of 24,16 and 32 = 96.
