One method for determining the LCM of 82 and 89 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 89's prime factorization:
89 | 89 |
1 |
Prime factors of 89 are 89.
89 = 891
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: 2,41,89
.21×411×891 = 7298
This shows that the LCM of 82 and 89 is 7298.
The first step in determining the Least Common Multiple of 82 and 89 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 82 and 89:
Lets look at the first ten multiples of these numbers, 82 and 89:
82,164,246,328,410,492,574,656,738,1394 are the first ten multiples of 82.
89,178,267,356,445,534,623,712,801,1513 are the first ten multiples of 89.
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 89, for example, are 984, 1394, and 1424. 7298 is the least common multiple since it is the smallest.
82 and 89 have an LCM of 7298.
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 82 and 89, than apply into the LCM equation.
GCF(82,89) = 1
LCM(82,89) = ( 82 × 89) / 1
LCM(82,89) = 7298 / 1
LCM(82,89) = 7298
