So, the LCM of 437, 445 is 194465.

One method for determining the LCM of 437 and 445 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 437's prime factorization:

Prime factors of 437 are 19,23.

437 = 19¹×23¹

And this is 445's prime factorization:

Prime factors of 445 are 5,89.

445 = 5¹×89¹

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: 19,23, 5,89

5¹×19¹×23¹×89¹ = 194465

This shows that the LCM of 437 and 445 is 194465.

The first step in determining the Least Common Multiple of 437 and 445 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 437 and 445:

Lets look at the first ten multiples of these numbers, 437 and 445:

437,874,1311,1748,2185,2622,3059,3496,3933,7429 are the first ten multiples of 437.

445,890,1335,1780,2225,2670,3115,3560,4005,7565 are the first ten multiples of 445.

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 437 and 445, for example, are 5244, 7429, and 7120. 194465 is the least common multiple since it is the smallest.

437 and 445 have an LCM of 194465.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 437 and 445, than apply into the LCM equation.

GCF(437,445) = 1
LCM(437,445) = ( 437 × 445) / 1
LCM(437,445) = 194465 / 1
LCM(437,445) = 194465
