So, the LCM of 385, 389 is 149765.

One method for determining the LCM of 385 and 389 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 385's prime factorization:

Prime factors of 385 are 5, 7,11.

385 = 5¹×7¹×11¹

And this is 389's prime factorization:

Prime factors of 389 are 389.

389 = 389¹

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: 5, 7,11,389

5¹×7¹×11¹×389¹ = 149765

This shows that the LCM of 385 and 389 is 149765.

The first step in determining the Least Common Multiple of 385 and 389 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 385 and 389:

Lets look at the first ten multiples of these numbers, 385 and 389:

385,770,1155,1540,1925,2310,2695,3080,3465,6545 are the first ten multiples of 385.

389,778,1167,1556,1945,2334,2723,3112,3501,6613 are the first ten multiples of 389.

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 385 and 389, for example, are 4620, 6545, and 6224. 149765 is the least common multiple since it is the smallest.

385 and 389 have an LCM of 149765.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 385 and 389, than apply into the LCM equation.

GCF(385,389) = 1
LCM(385,389) = ( 385 × 389) / 1
LCM(385,389) = 149765 / 1
LCM(385,389) = 149765
