One method for determining the LCM of 87 and 94 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 87's prime factorization:3 | 87 |
29 | 29 |
1 |
Prime factors of 87 are 3,29.
87 = 31×291
And this is 94's prime factorization:
2 | 94 |
47 | 47 |
1 |
Prime factors of 94 are 2,47.
94 = 21×471
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: 3,29, 2,47
.21×31×291×471 = 8178
This shows that the LCM of 87 and 94 is 8178.
The first step in determining the Least Common Multiple of 87 and 94 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 87 and 94:
Lets look at the first ten multiples of these numbers, 87 and 94:
87,174,261,348,435,522,609,696,783,1479 are the first ten multiples of 87.
94,188,282,376,470,564,658,752,846,1598 are the first ten multiples of 94.
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 87 and 94, for example, are 1044, 1479, and 1504. 8178 is the least common multiple since it is the smallest.
87 and 94 have an LCM of 8178.
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 87 and 94, than apply into the LCM equation.
GCF(87,94) = 1
LCM(87,94) = ( 87 × 94) / 1
LCM(87,94) = 8178 / 1
LCM(87,94) = 8178
