Multiples of 91 =91,182,273,364,455,546,637,728,819,910,1001,1092,1183,1274,1365,1456,1547,
Multiples of 95 =95,190,285,380,475,570,665,760,855,950,1045,1140,1235,1330,1425,1520,1615,
Now, get the least common multiple of 91, 95 which is 8645
So, the LCM of 91, 95 is 8645.
One method for determining the LCM of 91 and 95 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 91's prime factorization:7 | 91 |
13 | 13 |
1 |
Prime factors of 91 are 7,13.
91 = 71×131
And this is 95's prime factorization:
5 | 95 |
19 | 19 |
1 |
Prime factors of 95 are 5,19.
95 = 51×191
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: 7,13, 5,19
.51×71×131×191 = 8645
This shows that the LCM of 91 and 95 is 8645.
The first step in determining the Least Common Multiple of 91 and 95 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 91 and 95:
Lets look at the first ten multiples of these numbers, 91 and 95:
91,182,273,364,455,546,637,728,819,1547 are the first ten multiples of 91.
95,190,285,380,475,570,665,760,855,1615 are the first ten multiples of 95.
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 91 and 95, for example, are 1092, 1547, and 1520. 8645 is the least common multiple since it is the smallest.
91 and 95 have an LCM of 8645.
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 91 and 95, than apply into the LCM equation.
GCF(91,95) = 1
LCM(91,95) = ( 91 × 95) / 1
LCM(91,95) = 8645 / 1
LCM(91,95) = 8645
