LCM of 12 and 24 Using Listing the Multiples

To calculate the LCM of 12 and 24 using listing multiples, below are the steps to be followed:


Step 1: List a few multiples of 12 and 24 


12 - 12, 24, 36, 48, 60……


24 - 24, 48, 72, 96, 120…..

 

Step 2: From the multiples of 12 and 24, we can see that 24 and 48 are the common multiples of 12 and 24. 


Step 3: The smallest common multiple of 12 and 24 is 24


Therefore, the least common multiple of 12 and 24 is 24.

LCM of 12 and 24 Using Prime Factorization

To find the LCM of 12 and 24 using the Prime Factorization method:


Step 1: Find the prime factors of 12 and 24 


Prime factors of 12 = 2×2×3 = 22 × 3


Prime factors of 24 = 2×2×2×3 = 23 × 31 


Step 2: Now multiply prime factors raised to their respective highest power.


 i.e., 23 × 31 = 24.


Therefore, the LCM of 12 and 24 is 24

LCM of 12 and 24 Using Division Method

Here are the steps to find the LCM of 12 and 24 using the Division method:


Step 1: Write 12 and 24 in a row


Step 2: Find the smallest prime number that can divide either 12 or 24.


Here 2 is the smallest prime number.

 

Step 3: Divide and repeat the same process until you can’t divide anymore.


Step 4: After dividing, multiply all the prime numbers you used to divide.


Here, 2×2×3×2 = 24


Therefore, LCM of 12 and 24 is 24.
