What is LCM of 41 and 45

Given Numbers are 41, 45

We can find the LCM of 41, 45 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 41 and 45

Multiples of 41 =41,82,123,164,205,246,287,328,369,410,451,492,533,574,615,656,697,

Multiples of 45 =45,90,135,180,225,270,315,360,405,450,495,540,585,630,675,720,765,

Now, get the least common multiple of 41, 45 which is 1845

So, the LCM of 41, 45 is 1845.

Least Common Multiple (LCM) of 41 and 45 with the help of Prime Factorisation

One method for determining the LCM of 41 and 45 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 41's prime factorization:


41 41
1

Prime factors of 41 are 41.

41 = 411

And this is 45's prime factorization:


3 45
3 15
5 5
1

Prime factors of 45 are 3,5.

45 = 32×51

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:41, 3,5

.

32×51×411 = 1845

This shows that the LCM of 41 and 45 is 1845.

How to Calculate the LCM of 41 and 45 Using Common Multiples

The first step in determining the Least Common Multiple of 41 and 45 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 41 and 45:

Lets look at the first ten multiples of these numbers, 41 and 45:

41,82,123,164,205,246,287,328,369,697 are the first ten multiples of 41.

45,90,135,180,225,270,315,360,405,765 are the first ten multiples of 45.

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 41 and 45, for example, are 492, 697, and 720. 1845 is the least common multiple since it is the smallest.

41 and 45 have an LCM of 1845.

Least Common Multiple of 41 and 45 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 41 and 45, than apply into the LCM equation.

GCF(41,45) = 1
LCM(41,45) = ( 41 × 45) / 1
LCM(41,45) = 1845 / 1
LCM(41,45) = 1845
