The LCM is a tool that is used to find the smallest common number between the given numbers. It helps us to coordinate schedules, organizing and solving math problems. Let’s learn more about the LCM of 18,24 and 36.

What is the LCM of 18,24 and 36?

The LCM of 18,24 and 36 is 72.

This answer can be found using different methods, they are explained below.

How to find the LCM of 18,24 and 36?

The LCM can be found by using the listing multiples method, the prime factorization method and the division method.

Listing multiples method

In the listing multiples methods, we list down the multiples of each of the numbers and find the smallest common multiple from the list.

In case of 18,24 and 36;

Multiples of-

18 = 18,36,54,72,...

24=24,48,72,...

36 = 36,72,...

LCM(18,24,36) = 72

Prime factorization method

Here, we break the numbers to their prime factors and then multiply the highest powers of each of the factors to get the LCM.

In case of 18,24 and 36;

Step 1: Prime factorize the numbers,

18 = 3×3×2

24= 2×2×2×3

36 = 2×2×3×3

Step 2: Find the highest powers

Highest powers of 2 = 2³ , from 24

Highest powers of 3 = 3² , from 18 and 36

Step 3: LCM of the numbers is found by multiplying the highest powers

2³×3² = 8×9 = 72

LCM(18,24,36) = 72

Division method

Follow the below instructions to find the LCM using the division method;

1.Write the numbers, 18,24,36 in a row

2.Start dividing the numbers with a prime factor that is divisible by at least one of the numbers

3.Continue to bring down the numbers if they are left undivided by the previously chosen factor

4.Conclude the division when the result of the last row is just ‘1’.

5.Multiply the divisors on the first column to get the LCM.

LCM(18,24,36) = 72
