One method for determining the LCM of 338 and 343 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 338's prime factorization:

Prime factors of 338 are 2,13.

338 = 2¹×13²

And this is 343's prime factorization:

Prime factors of 343 are 7.

343 = 7³

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: 2,13,7

2¹×7³×13² = 115934

This shows that the LCM of 338 and 343 is 115934.

The first step in determining the Least Common Multiple of 338 and 343 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 338 and 343:

Lets look at the first ten multiples of these numbers, 338 and 343:

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

343,686,1029,1372,1715,2058,2401,2744,3087,5831 are the first ten multiples of 343.

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 338 and 343, for example, are 4056, 5746, and 5488. 115934 is the least common multiple since it is the smallest.

338 and 343 have an LCM of 115934.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 338 and 343, than apply into the LCM equation.

GCF(338,343) = 1
LCM(338,343) = ( 338 × 343) / 1
LCM(338,343) = 115934 / 1
LCM(338,343) = 115934
