Multiples of 285 =285,570,855,1140,1425,1710,1995,2280,2565,2850,3135,3420,3705,3990,4275,4560,4845,

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 285, 291 which is 27645

So, the LCM of 285, 291 is 27645.

One method for determining the LCM of 285 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 285's prime factorization:

Prime factors of 285 are 3, 5,19.

285 = 3¹×5¹×19¹

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: 3, 5,19,97

3¹×5¹×19¹×97¹ = 27645

This shows that the LCM of 285 and 291 is 27645.

The first step in determining the Least Common Multiple of 285 and 291 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 285 and 291:

Lets look at the first ten multiples of these numbers, 285 and 291:

285,570,855,1140,1425,1710,1995,2280,2565,4845 are the first ten multiples of 285.

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 285 and 291, for example, are 3420, 4845, and 4656. 27645 is the least common multiple since it is the smallest.

285 and 291 have an LCM of 27645.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 285 and 291, than apply into the LCM equation.

GCF(285,291) = 3
LCM(285,291) = ( 285 × 291) / 3
LCM(285,291) = 82935 / 3
LCM(285,291) = 27645
