How to Calculate LCM of Multiple Numbers?

The smallest positive integer that can be divided by a given set of numbers is known as the least common multiple. It is commonly referred as the lowest common multiple. There are multiple methods to calculate the LCM. They are the prime factorization method, division method & listing of multiples method.

LCM of 4 Numbers by Division Method Step by Step Calculation

Here are the steps to calculate the LCM of multiples numbers using the division method.

  1. Check the given numbers to calculate the LCM & write them in tabular format.
  2. Divide the numbers by using the smallest prime number (i.e. 2, 3, 5 & so on) & then write the quotient in the next line.
  3. Here, the point to be considered is that at least one number should be divisible by the smallest prime number.
  4. If a number is not divisible by a prime number, then write that number as it is in the next line.
  5. Keep dividing all the numbers in a table by the smallest prime number, so that we should get the final answer of the division as 1 for all numbers.
  6. Now, take all the smallest prime numbers together & multiply.
  7. Multiplication of all the prime numbers is the LCM of a given set of numbers.
