Multiples of 287 =287,574,861,1148,1435,1722,2009,2296,2583,2870,3157,3444,3731,4018,4305,4592,4879,

Multiples of 291 =291,582,873,1164,1455,1746,2037,2328,2619,2910,3201,3492,3783,4074,4365,4656,4947,

Now, get the least common multiple of 287, 291 which is 83517

So, the LCM of 287, 291 is 83517.

One method for determining the LCM of 287 and 291 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 287's prime factorization:

Prime factors of 287 are 7,41.

287 = 7¹×41¹

And this is 291's prime factorization:

Prime factors of 291 are 3,97.

291 = 3¹×97¹

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: 7,41, 3,97

3¹×7¹×41¹×97¹ = 83517

This shows that the LCM of 287 and 291 is 83517.

The first step in determining the Least Common Multiple of 287 and 291 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 287 and 291:

Lets look at the first ten multiples of these numbers, 287 and 291:

287,574,861,1148,1435,1722,2009,2296,2583,4879 are the first ten multiples of 287.

291,582,873,1164,1455,1746,2037,2328,2619,4947 are the first ten multiples of 291.

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 287 and 291, for example, are 3444, 4879, and 4656. 83517 is the least common multiple since it is the smallest.

287 and 291 have an LCM of 83517.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 287 and 291, than apply into the LCM equation.

GCF(287,291) = 1
LCM(287,291) = ( 287 × 291) / 1
LCM(287,291) = 83517 / 1
LCM(287,291) = 83517
