We can find the LCM of 380, 388 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 380 and 388

Multiples of 380 =380,760,1140,1520,1900,2280,2660,3040,3420,3800,4180,4560,4940,5320,5700,6080,6460,

Multiples of 388 =388,776,1164,1552,1940,2328,2716,3104,3492,3880,4268,4656,5044,5432,5820,6208,6596,

Now, get the least common multiple of 380, 388 which is 36860

So, the LCM of 380, 388 is 36860.

One method for determining the LCM of 380 and 388 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 380's prime factorization:

Prime factors of 380 are 2, 5,19.

380 = 2²×5¹×19¹

And this is 388's prime factorization:

Prime factors of 388 are 2,97.

388 = 2²×97¹

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, 5,19,97

2²×5¹×19¹×97¹ = 36860

This shows that the LCM of 380 and 388 is 36860.

The first step in determining the Least Common Multiple of 380 and 388 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 380 and 388:

Lets look at the first ten multiples of these numbers, 380 and 388:

380,760,1140,1520,1900,2280,2660,3040,3420,6460 are the first ten multiples of 380.

388,776,1164,1552,1940,2328,2716,3104,3492,6596 are the first ten multiples of 388.

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 380 and 388, for example, are 4560, 6460, and 6208. 36860 is the least common multiple since it is the smallest.

380 and 388 have an LCM of 36860.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 380 and 388, than apply into the LCM equation.

GCF(380,388) = 4
LCM(380,388) = ( 380 × 388) / 4
LCM(380,388) = 147440 / 4
LCM(380,388) = 36860
