Given Numbers are 11, 19

We can find the LCM of 11, 19 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 11 and 19

Multiples of 11 =11,22,33,44,55,66,77,88,99,110,121,132,143,154,165,176,187,

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 11, 19 which is 209

So, the LCM of 11, 19 is 209.

One method for determining the LCM of 11 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 11's prime factorization:

Prime factors of 11 are 11.

11 = 11¹

And this is 19's prime factorization:

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:11,19

11¹×19¹ = 209

This shows that the LCM of 11 and 19 is 209.

The first step in determining the Least Common Multiple of 11 and 19 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 11 and 19:

Lets look at the first ten multiples of these numbers, 11 and 19:

11,22,33,44,55,66,77,88,99,187 are the first ten multiples of 11.

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 11 and 19, for example, are 132, 187, and 304. 209 is the least common multiple since it is the smallest.

11 and 19 have an LCM of 209.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 11 and 19, than apply into the LCM equation.

GCF(11,19) = 1
LCM(11,19) = ( 11 × 19) / 1
LCM(11,19) = 209 / 1
LCM(11,19) = 209
