Given Numbers are 12, 19
We can find the LCM of 12, 19 using the brute force method, prime factorization method, or GCD method.
To use brute force method, list the multiples of 12 and 19
Multiples of 12 =12,24,36,48,60,72,84,96,108,120,132,144,156,168,180,192,204,
Multiples of 19 =19,38,57,76,95,114,133,152,171,190,209,228,247,266,285,304,323,
Now, get the least common multiple of 12, 19 which is 228
So, the LCM of 12, 19 is 228.
One method for determining the LCM of 12 and 19 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 19's prime factorization:
19 | 19 |
1 |
Prime factors of 19 are 19.
19 = 191
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: 2,3,19
.22×31×191 = 228
This shows that the LCM of 12 and 19 is 228.
The first step in determining the Least Common Multiple of 12 and 19 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 12 and 19:
Lets look at the first ten multiples of these numbers, 12 and 19:
12,24,36,48,60,72,84,96,108,204 are the first ten multiples of 12.
19,38,57,76,95,114,133,152,171,323 are the first ten multiples of 19.
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 19, for example, are 144, 204, and 304. 228 is the least common multiple since it is the smallest.
12 and 19 have an LCM of 228.
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 12 and 19, than apply into the LCM equation.
GCF(12,19) = 1
LCM(12,19) = ( 12 × 19) / 1
LCM(12,19) = 228 / 1
LCM(12,19) = 228
