What is LCM of 440 and 445

Given Numbers are 440, 445

We can find the LCM of 440, 445 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 440 and 445

Multiples of 440 =440,880,1320,1760,2200,2640,3080,3520,3960,4400,4840,5280,5720,6160,6600,7040,7480,

Multiples of 445 =445,890,1335,1780,2225,2670,3115,3560,4005,4450,4895,5340,5785,6230,6675,7120,7565,

Now, get the least common multiple of 440, 445 which is 39160

So, the LCM of 440, 445 is 39160.

Least Common Multiple (LCM) of 440 and 445 with the help of Prime Factorisation

One method for determining the LCM of 440 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 440's prime factorization:


2 440
2 220
2 110
5 55
11 11
1

Prime factors of 440 are 2, 5,11.

440 = 23×51×111

And this is 445's prime factorization:


5 445
89 89
1

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: 2, 5,11,89

.

23×51×111×891 = 39160

This shows that the LCM of 440 and 445 is 39160.

How to Calculate the LCM of 440 and 445 Using Common Multiples

The first step in determining the Least Common Multiple of 440 and 445 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 440 and 445:

Lets look at the first ten multiples of these numbers, 440 and 445:

440,880,1320,1760,2200,2640,3080,3520,3960,7480 are the first ten multiples of 440.

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 440 and 445, for example, are 5280, 7480, and 7120. 39160 is the least common multiple since it is the smallest.

440 and 445 have an LCM of 39160.

Least Common Multiple of 440 and 445 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 440 and 445, than apply into the LCM equation.

GCF(440,445) = 5
LCM(440,445) = ( 440 × 445) / 5
LCM(440,445) = 195800 / 5
LCM(440,445) = 39160
