Given Numbers are 271, 278

We can find the LCM of 271, 278 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 271 and 278

Multiples of 271 =271,542,813,1084,1355,1626,1897,2168,2439,2710,2981,3252,3523,3794,4065,4336,4607,

Multiples of 278 =278,556,834,1112,1390,1668,1946,2224,2502,2780,3058,3336,3614,3892,4170,4448,4726,

Now, get the least common multiple of 271, 278 which is 75338

So, the LCM of 271, 278 is 75338.

One method for determining the LCM of 271 and 278 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 271's prime factorization:

Prime factors of 271 are 271.

271 = 271¹

And this is 278's prime factorization:

Prime factors of 278 are 2,139.

278 = 2¹×139¹

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:271, 2,139

2¹×139¹×271¹ = 75338

This shows that the LCM of 271 and 278 is 75338.

The first step in determining the Least Common Multiple of 271 and 278 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 271 and 278:

Lets look at the first ten multiples of these numbers, 271 and 278:

271,542,813,1084,1355,1626,1897,2168,2439,4607 are the first ten multiples of 271.

278,556,834,1112,1390,1668,1946,2224,2502,4726 are the first ten multiples of 278.

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 271 and 278, for example, are 3252, 4607, and 4448. 75338 is the least common multiple since it is the smallest.

271 and 278 have an LCM of 75338.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 271 and 278, than apply into the LCM equation.

GCF(271,278) = 1
LCM(271,278) = ( 271 × 278) / 1
LCM(271,278) = 75338 / 1
LCM(271,278) = 75338
