Given Numbers are 115, 122

We can find the LCM of 115, 122 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 115 and 122

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

Multiples of 122 =122,244,366,488,610,732,854,976,1098,1220,1342,1464,1586,1708,1830,1952,2074,

Now, get the least common multiple of 115, 122 which is 14030

So, the LCM of 115, 122 is 14030.

One method for determining the LCM of 115 and 122 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 122's prime factorization:

Prime factors of 122 are 2,61.

122 = 2¹×61¹

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, 2,61

2¹×5¹×23¹×61¹ = 14030

This shows that the LCM of 115 and 122 is 14030.

The first step in determining the Least Common Multiple of 115 and 122 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 115 and 122:

Lets look at the first ten multiples of these numbers, 115 and 122:

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

122,244,366,488,610,732,854,976,1098,2074 are the first ten multiples of 122.

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 122, for example, are 1380, 1955, and 1952. 14030 is the least common multiple since it is the smallest.

115 and 122 have an LCM of 14030.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 115 and 122, than apply into the LCM equation.

GCF(115,122) = 1
LCM(115,122) = ( 115 × 122) / 1
LCM(115,122) = 14030 / 1
LCM(115,122) = 14030
