One method for determining the LCM of 79 and 87 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 79's prime factorization:79 | 79 |
1 |
Prime factors of 79 are 79.
79 = 791
And this is 87's prime factorization:
3 | 87 |
29 | 29 |
1 |
Prime factors of 87 are 3,29.
87 = 31×291
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:79, 3,29
.31×291×791 = 6873
This shows that the LCM of 79 and 87 is 6873.
The first step in determining the Least Common Multiple of 79 and 87 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 79 and 87:
Lets look at the first ten multiples of these numbers, 79 and 87:
79,158,237,316,395,474,553,632,711,1343 are the first ten multiples of 79.
87,174,261,348,435,522,609,696,783,1479 are the first ten multiples of 87.
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 79 and 87, for example, are 948, 1343, and 1392. 6873 is the least common multiple since it is the smallest.
79 and 87 have an LCM of 6873.
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 79 and 87, than apply into the LCM equation.
GCF(79,87) = 1
LCM(79,87) = ( 79 × 87) / 1
LCM(79,87) = 6873 / 1
LCM(79,87) = 6873
