How to find the LCM of 12, 14, and 16?

We have already read about how you can approach finding the LCM of 2 or more numbers. Here is a list of those methods which make it easy to find the LCMs:


Method 1: Listing of Multiples
Method 2: Prime Factorization
Method 3: Division Method


Now let us delve further into these three methods and how it benefits us.

LCM of 12, 14, and 16 Using Listing of Multiples Method

In this method, we will list all the multiples of 12, 14, and 16. Then we will try to find a multiple that is present in all numbers.


For example, 


Multiples of 12:
12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180, 192, 204, 216, 228, 240, 252, 264, 276, 288, 300, 312, 324, 336…


Multiples of 14:
14, 28, 42, 56, 70, 84, 98, 112, 126, 140, 154, 168, 182, 196, 210, 224, 238, 252, 266, 280, 294, 308, 322, 336,....


Multiples of 16:
16, 32, 48, 64, 80, 96, 112, 128, 144, 160, 176, 192, 208, 224, 240, 256, 272, 288, 304, 320, 336.

 

The LCM of 12, 14, and 16 is 366. 366 is the smallest number which can be divisible by 12, 14, and 16.

LCM of 12, 14, and 16 Using Prime Factorization

To find the LCM of 12, 14, and 16 using the prime factorization method, we need to find out the prime factors of the numbers. Then multiply the highest powers of the factors to get the LCM. 


Prime Factors of 12 are: 22 × 31.
Prime Factors of 14 are: 21 × 71.
Prime Factors of 16 are: 24


Multiply the highest power of the factors: 24 × 31 × 71 = 16 × 3 × 7 = 336


Therefore, the LCM of 12, 14, and 16 is 336

Professor Greenline from BrightChamps

LCM of 12, 14, and 16 Using Division Method

To calculate the LCM using the division method. We will divide the given numbers with their prime numbers. The prime numbers should at least divide any one of the given numbers. Divide the numbers till the remainder becomes 1. By multiplying the prime factors, one can get LCM.


For finding the LCM of 12, 14, and 16 we will use the following method.

 

 

 

 

 

 

 

 

 

 

By multiplying the prime divisors from the table, we will get the LCM of 12, 14, and 16.


2 × 2 × 2 × 2 × 3 × 7 = 168


The LCM of 12, 14, and 16 is 366.

LCM of 12, 14, and 16 Examples

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

Problem 1

If the LCM of 12, 14, y is 336. Find ‘y’

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

The value of y is 16
 

Explanation

 ‘y’ is a divisor of 336. Try different values for ‘y’ other than 12 and 14. Here, y = 16 because it is a divisor of 336. Hence, 336 is the LCM.

Problem 2

The radius of the circle is the LCM of 12, 14, and 16. Find the diameter of the circle.

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

The radius is 336, and the diameter is 672
 

Explanation

Here, 336 is the LCM. So, the radius of the circle is 336. To find the diameter → ‘d = 2r’. The diameter of the circle = 2r = 2 × 336 = 672

Problem 3

What is the difference between LCM and GCF of 12, 14, and 16?

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

The difference is 334
 

Explanation

 The LCM is 336 and the GCF is 2. Subtract them to get the result. Therefore, the difference of LCM and GCF is 334 (336–2)

Important Glossaries for the LCM of 12, 14, and 16

  • Prime Number: Any number that has only 2 factors is called a prime number.For 5 and 7, only common factors are 1 and the number itself.

 

  • Composite Number: Any number that has more than 2 factors is called a composite number. For example, 4, 8, and 10. 

 

  • Prime Factorization: It is breaking down a number into smaller prime numbers, then multiplied together, giving the same number.
