Given Numbers are 261, 266

We can find the LCM of 261, 266 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 261 and 266

Multiples of 261 =261,522,783,1044,1305,1566,1827,2088,2349,2610,2871,3132,3393,3654,3915,4176,4437,

Multiples of 266 =266,532,798,1064,1330,1596,1862,2128,2394,2660,2926,3192,3458,3724,3990,4256,4522,

Now, get the least common multiple of 261, 266 which is 69426

So, the LCM of 261, 266 is 69426.

One method for determining the LCM of 261 and 266 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 261's prime factorization:

Prime factors of 261 are 3,29.

261 = 3²×29¹

And this is 266's prime factorization:

Prime factors of 266 are 2, 7,19.

266 = 2¹×7¹×19¹

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: 3,29, 2, 7,19

2¹×3²×7¹×19¹×29¹ = 69426

This shows that the LCM of 261 and 266 is 69426.

The first step in determining the Least Common Multiple of 261 and 266 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 261 and 266:

Lets look at the first ten multiples of these numbers, 261 and 266:

261,522,783,1044,1305,1566,1827,2088,2349,4437 are the first ten multiples of 261.

266,532,798,1064,1330,1596,1862,2128,2394,4522 are the first ten multiples of 266.

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 261 and 266, for example, are 3132, 4437, and 4256. 69426 is the least common multiple since it is the smallest.

261 and 266 have an LCM of 69426.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 261 and 266, than apply into the LCM equation.

GCF(261,266) = 1
LCM(261,266) = ( 261 × 266) / 1
LCM(261,266) = 69426 / 1
LCM(261,266) = 69426
