Given Numbers are 19, 23

We can find the LCM of 19, 23 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 19 and 23

Multiples of 19 =19,38,57,76,95,114,133,152,171,190,209,228,247,266,285,304,323,

Multiples of 23 =23,46,69,92,115,138,161,184,207,230,253,276,299,322,345,368,391,

Now, get the least common multiple of 19, 23 which is 437

So, the LCM of 19, 23 is 437.

One method for determining the LCM of 19 and 23 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 19's prime factorization:

Prime factors of 19 are 19.

19 = 19¹

And this is 23's prime factorization:

Prime factors of 23 are 23.

23 = 23¹

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:19,23

19¹×23¹ = 437

This shows that the LCM of 19 and 23 is 437.

The first step in determining the Least Common Multiple of 19 and 23 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 19 and 23:

Lets look at the first ten multiples of these numbers, 19 and 23:

19,38,57,76,95,114,133,152,171,323 are the first ten multiples of 19.

23,46,69,92,115,138,161,184,207,391 are the first ten multiples of 23.

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 19 and 23, for example, are 228, 323, and 368. 437 is the least common multiple since it is the smallest.

19 and 23 have an LCM of 437.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 19 and 23, than apply into the LCM equation.

GCF(19,23) = 1
LCM(19,23) = ( 19 × 23) / 1
LCM(19,23) = 437 / 1
LCM(19,23) = 437
