So, the LCM of 164, 168 is 6888.

One method for determining the LCM of 164 and 168 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 164's prime factorization:

Prime factors of 164 are 2,41.

164 = 2²×41¹

And this is 168's prime factorization:

Prime factors of 168 are 2, 3,7.

168 = 2³×3¹×7¹

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: 2,41, 3,7

2³×3¹×7¹×41¹ = 6888

This shows that the LCM of 164 and 168 is 6888.

The first step in determining the Least Common Multiple of 164 and 168 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 164 and 168:

Lets look at the first ten multiples of these numbers, 164 and 168:

164,328,492,656,820,984,1148,1312,1476,2788 are the first ten multiples of 164.

168,336,504,672,840,1008,1176,1344,1512,2856 are the first ten multiples of 168.

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 164 and 168, for example, are 1968, 2788, and 2688. 6888 is the least common multiple since it is the smallest.

164 and 168 have an LCM of 6888.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 164 and 168, than apply into the LCM equation.

GCF(164,168) = 4
LCM(164,168) = ( 164 × 168) / 4
LCM(164,168) = 27552 / 4
LCM(164,168) = 6888
