What is LCM of 12 and 14

Given Numbers are 12, 14

We can find the LCM of 12, 14 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 12 and 14

Multiples of 12 =12,24,36,48,60,72,84,96,108,120,132,144,156,168,180,192,204,

Multiples of 14 =14,28,42,56,70,84,98,112,126,140,154,168,182,196,210,224,238,

Now, get the least common multiple of 12, 14 which is 84

So, the LCM of 12, 14 is 84.

Least Common Multiple (LCM) of 12 and 14 with the help of Prime Factorisation

One method for determining the LCM of 12 and 14 is to compare the prime factorization of each number. You can find the prime factorization for each number by following the instructions below:

Here is 12's prime factorization:


2 12
2 6
3 3
1

Prime factors of 12 are 2,3.

12 = 22×31

And this is 14's prime factorization:


2 14
7 7
1

Prime factors of 14 are 2,7.

14 = 21×71

When comparing the prime factorization of these two numbers, look for the highest power to which each prime factor is raised. In this case, the following primary factors must be considered: 2,3,7

.

22×31×71 = 84

This shows that the LCM of 12 and 14 is 84.

How to Calculate the LCM of 12 and 14 Using Common Multiples

The first step in determining the Least Common Multiple of 12 and 14 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 12 and 14:

Lets look at the first ten multiples of these numbers, 12 and 14:

12,24,36,48,60,72,84,96,108,204 are the first ten multiples of 12.

14,28,42,56,70,84,98,112,126,238 are the first ten multiples of 14.

You can continue to list the multiples of these numbers until you find a match. Once you have found a match, or several matches, the Least Common Multiple is the smallest of these matches. The first matching multiple(s) of 12 and 14, for example, are 144, 204, and 224. 84 is the least common multiple since it is the smallest.

12 and 14 have an LCM of 84.

Least Common Multiple of 12 and 14 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 12 and 14, than apply into the LCM equation.

GCF(12,14) = 2
LCM(12,14) = ( 12 × 14) / 2
LCM(12,14) = 168 / 2
LCM(12,14) = 84
