So, the LCM of 428, 433 is 185324.

One method for determining the LCM of 428 and 433 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 428's prime factorization:

Prime factors of 428 are 2,107.

428 = 2²×107¹

And this is 433's prime factorization:

Prime factors of 433 are 433.

433 = 433¹

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: 2,107,433

2²×107¹×433¹ = 185324

This shows that the LCM of 428 and 433 is 185324.

The first step in determining the Least Common Multiple of 428 and 433 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 428 and 433:

Lets look at the first ten multiples of these numbers, 428 and 433:

428,856,1284,1712,2140,2568,2996,3424,3852,7276 are the first ten multiples of 428.

433,866,1299,1732,2165,2598,3031,3464,3897,7361 are the first ten multiples of 433.

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 428 and 433, for example, are 5136, 7276, and 6928. 185324 is the least common multiple since it is the smallest.

428 and 433 have an LCM of 185324.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 428 and 433, than apply into the LCM equation.

GCF(428,433) = 1
LCM(428,433) = ( 428 × 433) / 1
LCM(428,433) = 185324 / 1
LCM(428,433) = 185324
