Given Numbers are 123, 127

We can find the LCM of 123, 127 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 123 and 127

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

Multiples of 127 =127,254,381,508,635,762,889,1016,1143,1270,1397,1524,1651,1778,1905,2032,2159,

Now, get the least common multiple of 123, 127 which is 15621

So, the LCM of 123, 127 is 15621.

One method for determining the LCM of 123 and 127 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 123's prime factorization:

Prime factors of 123 are 3,41.

123 = 3¹×41¹

And this is 127's prime factorization:

Prime factors of 127 are 127.

127 = 127¹

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: 3,41,127

3¹×41¹×127¹ = 15621

This shows that the LCM of 123 and 127 is 15621.

The first step in determining the Least Common Multiple of 123 and 127 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 123 and 127:

Lets look at the first ten multiples of these numbers, 123 and 127:

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

127,254,381,508,635,762,889,1016,1143,2159 are the first ten multiples of 127.

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 123 and 127, for example, are 1476, 2091, and 2032. 15621 is the least common multiple since it is the smallest.

123 and 127 have an LCM of 15621.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 123 and 127, than apply into the LCM equation.

GCF(123,127) = 1
LCM(123,127) = ( 123 × 127) / 1
LCM(123,127) = 15621 / 1
LCM(123,127) = 15621
