What is LCM of 128 and 136

Given Numbers are 128, 136

We can find the LCM of 128, 136 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 128 and 136

Multiples of 128 =128,256,384,512,640,768,896,1024,1152,1280,1408,1536,1664,1792,1920,2048,2176,

Multiples of 136 =136,272,408,544,680,816,952,1088,1224,1360,1496,1632,1768,1904,2040,2176,2312,

Now, get the least common multiple of 128, 136 which is 2176

So, the LCM of 128, 136 is 2176.

Least Common Multiple (LCM) of 128 and 136 with the help of Prime Factorisation

One method for determining the LCM of 128 and 136 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 128's prime factorization:


2 128
2 64
2 32
2 16
2 8
2 4
2 2
1

Prime factors of 128 are 2.

128 = 27

And this is 136's prime factorization:


2 136
2 68
2 34
17 17
1

Prime factors of 136 are 2,17.

136 = 23×171

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:2,17

.

27×171 = 2176

This shows that the LCM of 128 and 136 is 2176.

How to Calculate the LCM of 128 and 136 Using Common Multiples

The first step in determining the Least Common Multiple of 128 and 136 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 128 and 136:

Lets look at the first ten multiples of these numbers, 128 and 136:

128,256,384,512,640,768,896,1024,1152,2176 are the first ten multiples of 128.

136,272,408,544,680,816,952,1088,1224,2312 are the first ten multiples of 136.

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 128 and 136, for example, are 1536, 2176, and 2176. 2176 is the least common multiple since it is the smallest.

128 and 136 have an LCM of 2176.

Least Common Multiple of 128 and 136 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 128 and 136, than apply into the LCM equation.

GCF(128,136) = 8
LCM(128,136) = ( 128 × 136) / 8
LCM(128,136) = 17408 / 8
LCM(128,136) = 2176
