Least Common Multiple (LCM) of 34 and 39 with the help of Prime Factorisation
One method for determining the LCM of 34 and 39 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 34's prime factorization:
| 2 | 34 |
| 17 | 17 |
| 1 |
Prime factors of 34 are 2,17.
34 = 21×171
And this is 39's prime factorization:
| 3 | 39 |
| 13 | 13 |
| 1 |
Prime factors of 39 are 3,13.
39 = 31×131
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: 2,17, 3,13
.21×31×131×171 = 1326
This shows that the LCM of 34 and 39 is 1326.
How to Calculate the LCM of 34 and 39 Using Common Multiples
The first step in determining the Least Common Multiple of 34 and 39 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 34 and 39:
Lets look at the first ten multiples of these numbers, 34 and 39:
34,68,102,136,170,204,238,272,306,578 are the first ten multiples of 34.
39,78,117,156,195,234,273,312,351,663 are the first ten multiples of 39.
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 34 and 39, for example, are 408, 578, and 624. 1326 is the least common multiple since it is the smallest.
34 and 39 have an LCM of 1326.
Least Common Multiple of 34 and 39 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 34 and 39, than apply into the LCM equation.
GCF(34,39) = 1
LCM(34,39) = ( 34 × 39) / 1
LCM(34,39) = 1326 / 1
LCM(34,39) = 1326
