One method for determining the LCM of 383 and 390 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 383's prime factorization:

Prime factors of 383 are 383.

383 = 383¹

And this is 390's prime factorization:

Prime factors of 390 are 2, 3, 5,13.

390 = 2¹×3¹×5¹×13¹

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:383, 2, 3, 5,13

2¹×3¹×5¹×13¹×383¹ = 149370

This shows that the LCM of 383 and 390 is 149370.

The first step in determining the Least Common Multiple of 383 and 390 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 383 and 390:

Lets look at the first ten multiples of these numbers, 383 and 390:

383,766,1149,1532,1915,2298,2681,3064,3447,6511 are the first ten multiples of 383.

390,780,1170,1560,1950,2340,2730,3120,3510,6630 are the first ten multiples of 390.

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 383 and 390, for example, are 4596, 6511, and 6240. 149370 is the least common multiple since it is the smallest.

383 and 390 have an LCM of 149370.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 383 and 390, than apply into the LCM equation.

GCF(383,390) = 1
LCM(383,390) = ( 383 × 390) / 1
LCM(383,390) = 149370 / 1
LCM(383,390) = 149370
