What is LCM of 83 and 91

Given Numbers are 83, 91

We can find the LCM of 83, 91 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 83 and 91

Multiples of 83 =83,166,249,332,415,498,581,664,747,830,913,996,1079,1162,1245,1328,1411,

Multiples of 91 =91,182,273,364,455,546,637,728,819,910,1001,1092,1183,1274,1365,1456,1547,

Now, get the least common multiple of 83, 91 which is 7553

So, the LCM of 83, 91 is 7553.

Least Common Multiple (LCM) of 83 and 91 with the help of Prime Factorisation

One method for determining the LCM of 83 and 91 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 83's prime factorization:


83 83
1

Prime factors of 83 are 83.

83 = 831

And this is 91's prime factorization:


7 91
13 13
1

Prime factors of 91 are 7,13.

91 = 71×131

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:83, 7,13

.

71×131×831 = 7553

This shows that the LCM of 83 and 91 is 7553.

How to Calculate the LCM of 83 and 91 Using Common Multiples

The first step in determining the Least Common Multiple of 83 and 91 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 83 and 91:

Lets look at the first ten multiples of these numbers, 83 and 91:

83,166,249,332,415,498,581,664,747,1411 are the first ten multiples of 83.

91,182,273,364,455,546,637,728,819,1547 are the first ten multiples of 91.

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 83 and 91, for example, are 996, 1411, and 1456. 7553 is the least common multiple since it is the smallest.

83 and 91 have an LCM of 7553.

Least Common Multiple of 83 and 91 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 83 and 91, than apply into the LCM equation.

GCF(83,91) = 1
LCM(83,91) = ( 83 × 91) / 1
LCM(83,91) = 7553 / 1
LCM(83,91) = 7553
