So, the LCM of 386, 391 is 150926.

One method for determining the LCM of 386 and 391 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 386's prime factorization:

Prime factors of 386 are 2,193.

386 = 2¹×193¹

And this is 391's prime factorization:

Prime factors of 391 are 17,23.

391 = 17¹×23¹

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: 2,193, 17,23

2¹×17¹×23¹×193¹ = 150926

This shows that the LCM of 386 and 391 is 150926.

The first step in determining the Least Common Multiple of 386 and 391 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 386 and 391:

Lets look at the first ten multiples of these numbers, 386 and 391:

386,772,1158,1544,1930,2316,2702,3088,3474,6562 are the first ten multiples of 386.

391,782,1173,1564,1955,2346,2737,3128,3519,6647 are the first ten multiples of 391.

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 386 and 391, for example, are 4632, 6562, and 6256. 150926 is the least common multiple since it is the smallest.

386 and 391 have an LCM of 150926.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 386 and 391, than apply into the LCM equation.

GCF(386,391) = 1
LCM(386,391) = ( 386 × 391) / 1
LCM(386,391) = 150926 / 1
LCM(386,391) = 150926
