Given Numbers are 115, 123

We can find the LCM of 115, 123 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 115 and 123

Multiples of 115 =115,230,345,460,575,690,805,920,1035,1150,1265,1380,1495,1610,1725,1840,1955,

Multiples of 123 =123,246,369,492,615,738,861,984,1107,1230,1353,1476,1599,1722,1845,1968,2091,

Now, get the least common multiple of 115, 123 which is 14145

So, the LCM of 115, 123 is 14145.

One method for determining the LCM of 115 and 123 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 115's prime factorization:

Prime factors of 115 are 5,23.

115 = 5¹×23¹

And this is 123's prime factorization:

Prime factors of 123 are 3,41.

123 = 3¹×41¹

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: 5,23, 3,41

3¹×5¹×23¹×41¹ = 14145

This shows that the LCM of 115 and 123 is 14145.

The first step in determining the Least Common Multiple of 115 and 123 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 115 and 123:

Lets look at the first ten multiples of these numbers, 115 and 123:

115,230,345,460,575,690,805,920,1035,1955 are the first ten multiples of 115.

123,246,369,492,615,738,861,984,1107,2091 are the first ten multiples of 123.

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 115 and 123, for example, are 1380, 1955, and 1968. 14145 is the least common multiple since it is the smallest.

115 and 123 have an LCM of 14145.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 115 and 123, than apply into the LCM equation.

GCF(115,123) = 1
LCM(115,123) = ( 115 × 123) / 1
LCM(115,123) = 14145 / 1
LCM(115,123) = 14145
