So, the LCM of 27, 34 is 918.
Least Common Multiple (LCM) of 27 and 34 with the help of Prime Factorisation
One method for determining the LCM of 27 and 34 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 27's prime factorization:
| 3 | 27 |
| 3 | 9 |
| 3 | 3 |
| 1 |
Prime factors of 27 are 3.
27 = 33
And this is 34's prime factorization:
| 2 | 34 |
| 17 | 17 |
| 1 |
Prime factors of 34 are 2,17.
34 = 21×171
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, 2,17
.21×33×171 = 918
This shows that the LCM of 27 and 34 is 918.
How to Calculate the LCM of 27 and 34 Using Common Multiples
The first step in determining the Least Common Multiple of 27 and 34 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 27 and 34:
Lets look at the first ten multiples of these numbers, 27 and 34:
27,54,81,108,135,162,189,216,243,459 are the first ten multiples of 27.
34,68,102,136,170,204,238,272,306,578 are the first ten multiples of 34.
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 27 and 34, for example, are 324, 459, and 544. 918 is the least common multiple since it is the smallest.
27 and 34 have an LCM of 918.
Least Common Multiple of 27 and 34 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 27 and 34, than apply into the LCM equation.
GCF(27,34) = 1
LCM(27,34) = ( 27 × 34) / 1
LCM(27,34) = 918 / 1
LCM(27,34) = 918
