LCM Of 22 And 33

Professor Greenline Explaining Math Concepts

The Least Common Multiple (LCM) is the smallest number that when we divide by two or more numbers at a time, all three or more numbers divide into it. LCM also helps in math problems and everyday things like event planning or buying supplies. We will find the LCM of 22 and 33 together and what that really means.

What Is The LCM Of 22 And 33?

The LCM or the least common multiple of 2 numbers is the smallest number that appears as a multiple of both numbers. In the case of 22 and 33, The LCM is 66. But how did we get to this answer? There are different ways to obtain a LCM of 2 or more numbers. Let us take a look at those methods.

How To Find The LCM Of 22 And 33

Remember that we previously said there are plenty of ways to calculate the LCM of two numbers or more. Then some of those methods make it extremely easy for us to find the LCM of any two numbers. Those methods are: 

 

 

  • Listing of Multiples

 

  • Prime Factorization

 

  • Division Method

Finally, now we will learn how each of these methods can help us to calculate the LCM of given numbers.

Finding LCM Of 22 And 33 By Listing Of Multiples

This method will help us find the LCM of the numbers by listing the multiples of the given numbers. Let us take a step by step look at this method.

 

Step 1: The first step is to list all the multiples of the given numbers.

 

Multiples Of 22: 22, 44, 66, 88, 110, 132, 154, 176, 198 and 220


Multiples Of 33: 33, 66, 99, 132, 165, 198, 231, 264, 297 and 330.


Step 2: The second step is to find the smallest common multiples in both the numbers. In this case, that number is 66 as highlighted above.


By this way, we will be able to tell the LCM of given numbers.

Professor Greenline from BrightChamps

Finding The LCM By Prime Factorization

Let us break down the process of prime factorization into steps and make it easy for children to understand.


The first step is to break down the given numbers into its primal form. The primal form of the number is:


22= 11×2


33= 11×3


As you can see, 11 appears as a prime factor in both numbers. So instead of considering 11 two times, we will only consider it once. So the final equation will look like (11×3×2).


So after the multiplication, we will be getting the LCM as 66.


As you can see, using this method can be easier for larger numbers compared to the previous method.

Finding The LCM By Division Method

The method to calculate the LCM is really simple. We’ll break these given numbers apart till it comes down to one, by dividing it by the prime factors. The product of the divisors that will come is the LCM of the given numbers.


Let us understand it step by step:


The first thing is to find the number common in both the numbers. Here it is 11. In that case, we divide both the numbers by 11. It will reduce the values of the numbers to 2 and 3.


2 and 3 are a prime number, it can be divided by only 2 and 3. That means after dividing, there will be only 1’s in the last row.


This is the end of the division. However, we will now find the product of the numbers on the left. The numbers on the left side are 2, 3, and 11. 


These numbers multiplied give 66. On this basis, therefore, the LCM of the 22 and 33 becomes 66.

LCM Of 22 And 33 Examples

Ray, the Character from BrightChamps Explaining Math Concepts
Max, the Girl Character from BrightChamps

Problem 1

If two events repeat every 22 and 33 days, when do they overlap first?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The two events overlap on day 66, as it is the first day that both cycles of 22 and 33 days match up

Explanation

We find the overlap by using the smallest number that both 22 and 33 divide into without leaving a remainder. This number is 66.

Problem 2

Emma jogs every 22 days and Leo every 33 days. How many days until they jog together?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

 Emma and Leo will jog together every 66 days, as 66 is the smallest number that both 22 and 33 divide evenly into.
 

Explanation

To find when they jog together, we find the Least Common Multiple (LCM) of 22 and 33, which is 66.

Problem 3

Two trains pass by every 22 and 33 minutes. How long until they pass together again?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The trains will pass together every 66 minutes.
 

Explanation

 Since 66 is the smallest number both 22 and 33 divided evenly, both trains will meet again after 66 minutes.

Problem 4

Two water fountains turn on every 22 and 33 seconds. When will they turn on at the same time?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Both water fountains will turn on together every 66 seconds.
 

Explanation

66 seconds is the shortest time that fits both schedules. It’s the least common multiple of 22 and 33, when both match up.

Problem 5

In how many days do 22- and 33-day events first match?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The 22- and 33-day events will first match in 66 days.

Explanation

 We find the smallest day they match by calculating the Least Common Multiple (LCM). For 22 and 33, the LCM is 66 days.

Important Glossaries for LCM of 22 qnd 33

  • Least Common Multiple (LCM): The smallest number that can be evenly divided by two or more numbers without any leftovers.

 

  • Multiple: A number that can be obtained by multiplying a given number by an integer (e.g., multiples of 2 are 2, 4, 6, 8, etc.).

 

  • Prime Factorization: Breaking down a number into its prime factors. For example, the prime factorization of 22 is 2 × 11.

 

  • Divisor: A number that divides another number evenly. For example, 3 is a divisor of 12 because 12 ÷ 3 = 4.
