What is LCM of 12 and 17
Given Numbers are 12, 17
We can find the LCM of 12, 17 using the brute force method, prime factorization method, or GCD method.
To use brute force method, list the multiples of 12 and 17
Multiples of 12 =12,24,36,48,60,72,84,96,108,120,132,144,156,168,180,192,204,
Multiples of 17 =17,34,51,68,85,102,119,136,153,170,187,204,221,238,255,272,289,
Now, get the least common multiple of 12, 17 which is 204
So, the LCM of 12, 17 is 204.
Least Common Multiple (LCM) of 12 and 17 with the help of Prime Factorisation
One method for determining the LCM of 12 and 17 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 17's prime factorization:
| 17 | 17 |
| 1 |
Prime factors of 17 are 17.
17 = 171
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: 2,3,17
.22×31×171 = 204
This shows that the LCM of 12 and 17 is 204.
How to Calculate the LCM of 12 and 17 Using Common Multiples
The first step in determining the Least Common Multiple of 12 and 17 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 12 and 17:
Lets look at the first ten multiples of these numbers, 12 and 17:
12,24,36,48,60,72,84,96,108,204 are the first ten multiples of 12.
17,34,51,68,85,102,119,136,153,289 are the first ten multiples of 17.
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 17, for example, are 144, 204, and 272. 204 is the least common multiple since it is the smallest.
12 and 17 have an LCM of 204.
Least Common Multiple of 12 and 17 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 17, than apply into the LCM equation.
GCF(12,17) = 1
LCM(12,17) = ( 12 × 17) / 1
LCM(12,17) = 204 / 1
LCM(12,17) = 204
