So, the LCM of 331, 338 is 111878.

One method for determining the LCM of 331 and 338 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 331's prime factorization:

Prime factors of 331 are 331.

331 = 331¹

And this is 338's prime factorization:

Prime factors of 338 are 2,13.

338 = 2¹×13²

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:331, 2,13

2¹×13²×331¹ = 111878

This shows that the LCM of 331 and 338 is 111878.

The first step in determining the Least Common Multiple of 331 and 338 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 331 and 338:

Lets look at the first ten multiples of these numbers, 331 and 338:

331,662,993,1324,1655,1986,2317,2648,2979,5627 are the first ten multiples of 331.

338,676,1014,1352,1690,2028,2366,2704,3042,5746 are the first ten multiples of 338.

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 331 and 338, for example, are 3972, 5627, and 5408. 111878 is the least common multiple since it is the smallest.

331 and 338 have an LCM of 111878.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 331 and 338, than apply into the LCM equation.

GCF(331,338) = 1
LCM(331,338) = ( 331 × 338) / 1
LCM(331,338) = 111878 / 1
LCM(331,338) = 111878
