Given Numbers are 256, 260

We can find the LCM of 256, 260 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 256 and 260

Multiples of 256 =256,512,768,1024,1280,1536,1792,2048,2304,2560,2816,3072,3328,3584,3840,4096,4352,

Multiples of 260 =260,520,780,1040,1300,1560,1820,2080,2340,2600,2860,3120,3380,3640,3900,4160,4420,

Now, get the least common multiple of 256, 260 which is 16640

So, the LCM of 256, 260 is 16640.

One method for determining the LCM of 256 and 260 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 256's prime factorization:

Prime factors of 256 are 2.

256 = 2⁸

And this is 260's prime factorization:

Prime factors of 260 are 2, 5,13.

260 = 2²×5¹×13¹

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, 5,13

2⁸×5¹×13¹ = 16640

This shows that the LCM of 256 and 260 is 16640.

The first step in determining the Least Common Multiple of 256 and 260 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 256 and 260:

Lets look at the first ten multiples of these numbers, 256 and 260:

256,512,768,1024,1280,1536,1792,2048,2304,4352 are the first ten multiples of 256.

260,520,780,1040,1300,1560,1820,2080,2340,4420 are the first ten multiples of 260.

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 256 and 260, for example, are 3072, 4352, and 4160. 16640 is the least common multiple since it is the smallest.

256 and 260 have an LCM of 16640.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 256 and 260, than apply into the LCM equation.

GCF(256,260) = 4
LCM(256,260) = ( 256 × 260) / 4
LCM(256,260) = 66560 / 4
LCM(256,260) = 16640
