So, the LCM of 418, 422 is 88198.

One method for determining the LCM of 418 and 422 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 418's prime factorization:

Prime factors of 418 are 2, 11,19.

418 = 2¹×11¹×19¹

And this is 422's prime factorization:

Prime factors of 422 are 2,211.

422 = 2¹×211¹

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, 11,19,211

2¹×11¹×19¹×211¹ = 88198

This shows that the LCM of 418 and 422 is 88198.

The first step in determining the Least Common Multiple of 418 and 422 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 418 and 422:

Lets look at the first ten multiples of these numbers, 418 and 422:

418,836,1254,1672,2090,2508,2926,3344,3762,7106 are the first ten multiples of 418.

422,844,1266,1688,2110,2532,2954,3376,3798,7174 are the first ten multiples of 422.

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 418 and 422, for example, are 5016, 7106, and 6752. 88198 is the least common multiple since it is the smallest.

418 and 422 have an LCM of 88198.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 418 and 422, than apply into the LCM equation.

GCF(418,422) = 2
LCM(418,422) = ( 418 × 422) / 2
LCM(418,422) = 176396 / 2
LCM(418,422) = 88198
