So, the LCM of 27, 35 is 945.
Least Common Multiple (LCM) of 27 and 35 with the help of Prime Factorisation
One method for determining the LCM of 27 and 35 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 35's prime factorization:
| 5 | 35 |
| 7 | 7 |
| 1 |
Prime factors of 35 are 5,7.
35 = 51×71
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, 5,7
.33×51×71 = 945
This shows that the LCM of 27 and 35 is 945.
How to Calculate the LCM of 27 and 35 Using Common Multiples
The first step in determining the Least Common Multiple of 27 and 35 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 27 and 35:
Lets look at the first ten multiples of these numbers, 27 and 35:
27,54,81,108,135,162,189,216,243,459 are the first ten multiples of 27.
35,70,105,140,175,210,245,280,315,595 are the first ten multiples of 35.
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 35, for example, are 324, 459, and 560. 945 is the least common multiple since it is the smallest.
27 and 35 have an LCM of 945.
Least Common Multiple of 27 and 35 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 35, than apply into the LCM equation.
GCF(27,35) = 1
LCM(27,35) = ( 27 × 35) / 1
LCM(27,35) = 945 / 1
LCM(27,35) = 945
