LCM of 32 and 48

Professor Greenline Explaining Math Concepts

The Least common multiple (LCM) is the smallest number that is divisible by the numbers 32 and 48. The LCM can be found using the listing multiples method, the prime factorization and/or division methods. LCM helps to solve problems with fractions and scenarios like scheduling or aligning repeating cycle of events.

How to Find the LCM of 32 and 48?

There are various methods to find the LCM, Listing method, prime factorization method and division method are explained below;

LCM of 32 and 48 using the Listing Multiples Method

The LCM of 32 and 48 can be calculated using the following steps:

 

Step 1: Write down the multiples of each number


Multiples of 32 = 32,64,96,…


Multiples of 48 =48,96,144,…


Step 2: Ascertain the smallest multiple from the listed multiples:


 The smallest common multiple is 96.


Thus, LCM(32,48) = 96

Professor Greenline from BrightChamps

LCM of 32 and 48 using the Prime Factorization Method

The prime factors of each number are written, and then the highest power of the prime factors is multiplied to get the LCM.


Step 1: Find the prime factors of each number


Prime factorization of 32 = 22×32


Prime factorization of 48 = 24×3

 

Step 1: Take the highest powers of each prime factor and multiply the highest powers to get the LCM:
LCM(32,48) = 96

Professor Greenline from BrightChamps

LCM of 32 and 48 using the Division Method

This method involves dividing both numbers by their common prime factors and multiplying the divisors to find the LCM.
 

Step 1: Write the numbers, divide by common prime factors and multiply the divisors.

 

 

Step 2: A prime integer that is evenly divisible into at least one of the provided numbers should be used to divide the row of numbers. Continue dividing the numbers until the last row of the results is ‘1’ and bring down the numbers not divisible by the previously chosen prime number.

 

 

The LCM of the numbers is the product of the prime numbers in the first column, i.e, 


2×2×2×2×2×3 = 96


Thus, LCM(32,48) = 96

Mistake 1

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

 Confusing between LCM and HCF of the numbers 32 and 48
 

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

It is common for one to be confused between the HCF (Highest common factor) and LCM (least common multiple). LCM is the smallest number divisible by 32 and 48 while, the largest number that divides them both is the HCF. 


A simple trick to remember is that the HCF is going to be a relatively smaller number, it deals with divisors. 
For LCM, however, the number will be at least as large as the largest of the two numbers.


In the given case, the HCF is 8, and the LCM is 96.

Problem 1

A radio station plays the advertisement for beauty products every 32 minutes and an advertisement for stationery every 48 minutes. If they both start at the same time now, after how long will they both play together again?

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

 The LCM of 32 and 48 is 144. 
 

Explanation

The LCM of 32 and 48 is 144, which is the smallest common time interval for the given digits.

Problem 2

Traffic light A changes every 32 minutes and traffic light B switches every 48 minutes. When will they next turn green simultaneously.

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

We use the formula;  


LCM(a, b) = a×b/HCF(a, b) where, a=32, b=48


HCF of 32 and 48; 


Factors of 32 = 1,2,4,8,16,32


Factors of 48 = 1,2,3,4,6,8,12,24,48


HCF(32,48)= 8 


Applying the ascertained HCF in the formula; 


LCM(a, b) = a×b/HCF(a, b) 


LCM(32,48) = 32×48/8  = 96 


LCM(32,48) = 96 
 

Explanation

The traffic lights will change simultaneously in 96 minutes.
