Least Common Multiple (LCM) of 82 and 86 with the help of Prime Factorisation
One method for determining the LCM of 82 and 86 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 82's prime factorization:
| 2 | 82 |
| 41 | 41 |
| 1 |
Prime factors of 82 are 2,41.
82 = 21×411
And this is 86's prime factorization:
| 2 | 86 |
| 43 | 43 |
| 1 |
Prime factors of 86 are 2,43.
86 = 21×431
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: 2,41,43
.21×411×431 = 3526
This shows that the LCM of 82 and 86 is 3526.
How to Calculate the LCM of 82 and 86 Using Common Multiples
The first step in determining the Least Common Multiple of 82 and 86 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 82 and 86:
Lets look at the first ten multiples of these numbers, 82 and 86:
82,164,246,328,410,492,574,656,738,1394 are the first ten multiples of 82.
86,172,258,344,430,516,602,688,774,1462 are the first ten multiples of 86.
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 82 and 86, for example, are 984, 1394, and 1376. 3526 is the least common multiple since it is the smallest.
82 and 86 have an LCM of 3526.
Least Common Multiple of 82 and 86 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 82 and 86, than apply into the LCM equation.
GCF(82,86) = 2
LCM(82,86) = ( 82 × 86) / 2
LCM(82,86) = 7052 / 2
LCM(82,86) = 3526
