Given Numbers are 129, 137

We can find the LCM of 129, 137 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 129 and 137

Multiples of 129 =129,258,387,516,645,774,903,1032,1161,1290,1419,1548,1677,1806,1935,2064,2193,

Multiples of 137 =137,274,411,548,685,822,959,1096,1233,1370,1507,1644,1781,1918,2055,2192,2329,

Now, get the least common multiple of 129, 137 which is 17673

So, the LCM of 129, 137 is 17673.

One method for determining the LCM of 129 and 137 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 129's prime factorization:

Prime factors of 129 are 3,43.

129 = 3¹×43¹

And this is 137's prime factorization:

Prime factors of 137 are 137.

137 = 137¹

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: 3,43,137

3¹×43¹×137¹ = 17673

This shows that the LCM of 129 and 137 is 17673.

The first step in determining the Least Common Multiple of 129 and 137 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 129 and 137:

Lets look at the first ten multiples of these numbers, 129 and 137:

129,258,387,516,645,774,903,1032,1161,2193 are the first ten multiples of 129.

137,274,411,548,685,822,959,1096,1233,2329 are the first ten multiples of 137.

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 129 and 137, for example, are 1548, 2193, and 2192. 17673 is the least common multiple since it is the smallest.

129 and 137 have an LCM of 17673.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 129 and 137, than apply into the LCM equation.

GCF(129,137) = 1
LCM(129,137) = ( 129 × 137) / 1
LCM(129,137) = 17673 / 1
LCM(129,137) = 17673
