Given Numbers are 79, 86

We can find the LCM of 79, 86 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 79 and 86

Multiples of 79 =79,158,237,316,395,474,553,632,711,790,869,948,1027,1106,1185,1264,1343,

Multiples of 86 =86,172,258,344,430,516,602,688,774,860,946,1032,1118,1204,1290,1376,1462,

Now, get the least common multiple of 79, 86 which is 6794

So, the LCM of 79, 86 is 6794.

One method for determining the LCM of 79 and 86 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:

Prime factors of 79 are 79.

79 = 79¹

And this is 86's prime factorization:

Prime factors of 86 are 2,43.

86 = 2¹×43¹

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, 2,43

2¹×43¹×79¹ = 6794

This shows that the LCM of 79 and 86 is 6794.

The first step in determining the Least Common Multiple of 79 and 86 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 79 and 86:

Lets look at the first ten multiples of these numbers, 79 and 86:

79,158,237,316,395,474,553,632,711,1343 are the first ten multiples of 79.

86,172,258,344,430,516,602,688,774,1462 are the first ten multiples of 86.

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 86, for example, are 948, 1343, and 1376. 6794 is the least common multiple since it is the smallest.

79 and 86 have an LCM of 6794.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 79 and 86, than apply into the LCM equation.

GCF(79,86) = 1
LCM(79,86) = ( 79 × 86) / 1
LCM(79,86) = 6794 / 1
LCM(79,86) = 6794
