So, the LCM of 386, 393 is 151698.

One method for determining the LCM of 386 and 393 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 393's prime factorization:

Prime factors of 393 are 3,131.

393 = 3¹×131¹

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, 3,131

2¹×3¹×131¹×193¹ = 151698

This shows that the LCM of 386 and 393 is 151698.

The first step in determining the Least Common Multiple of 386 and 393 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 386 and 393:

Lets look at the first ten multiples of these numbers, 386 and 393:

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

393,786,1179,1572,1965,2358,2751,3144,3537,6681 are the first ten multiples of 393.

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 393, for example, are 4632, 6562, and 6288. 151698 is the least common multiple since it is the smallest.

386 and 393 have an LCM of 151698.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 386 and 393, than apply into the LCM equation.

GCF(386,393) = 1
LCM(386,393) = ( 386 × 393) / 1
LCM(386,393) = 151698 / 1
LCM(386,393) = 151698
