LCM of 2 and 12

Professor Greenline Explaining Math Concepts

The Least common multiple (LCM) is the smallest number that is divisible by the numbers 2 and 12. The LCM can be found using the listing multiples method, the prime factorization and/or division methods. In our daily life, we use cars without understanding the rotation of wheel caused due to LCM.

LCM of 2 and 12 using the Listing Multiples Method

The LCM of 2 and 12 can be calculated using the following steps:


Step 1: Write down the multiples of each number


Multiples of 2 = 2,4,6,8,10,12,…


Multiples of 12 = 12, 24, 36, …

 

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


The smallest common multiple is 12.


Thus, LCM(2, 12) = 12.

LCM of 2 and 12 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 the numbers:


Prime factorization of 2 = 2


 Prime factorization of 12 = 2 × 2 × 3


Step 2: Take the highest powers of each prime factor:


Highest power of 2 = 2²


Highest power of 2 = 2¹


Step 3:Multiply the highest powers to get the LCM:


LCM(2, 12) = 2² × 3 = 12.

LCM of 2 and 12 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; 2, 12 and divide by common prime factors and multiply the divisors.

 

 

Step 2: keep dividing untill we get 1 as remainder.

 

 

2 × 2 × 3 = 12


Thus, LCM(2, 12) = 12.
