## How do you find the least common multiple with LCM?

How to Find LCM by Listing Multiples

- List the multiples of each number until at least one of the multiples appears on all lists.
- Find the smallest number that is on all of the lists.
- This number is the LCM.

### How do you find the LCM of a set of integers?

A more systematic way to find the LCM of some given integers is to use prime factorization. Prime factorization involves breaking down each of the numbers being compared into its product of prime numbers.

**How do you find the least common multiple of 6 and 15?**

Example: Find the least common multiple (LCM) of 6 and 15 using the common division method. Step 1 – 2 is the smallest prime number and it is a factor of 6. Write this prime number on the left of the two numbers. For each number in the right column, continue finding out prime numbers which are their factors.

## What is the LCM and HCF of two or more numbers?

LCM of two or more numbers is always greater than or equal to each of the numbers. HCF of two or more numbers is always less than or equal to each of the numbers. The least common multiple of two or more numbers is having a wide number of properties. Given below are the three most common properties of the LCM:
