What is LCM of 320 and 325

Given Numbers are 320, 325

We can find the LCM of 320, 325 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 320 and 325

Multiples of 320 =320,640,960,1280,1600,1920,2240,2560,2880,3200,3520,3840,4160,4480,4800,5120,5440,

Multiples of 325 =325,650,975,1300,1625,1950,2275,2600,2925,3250,3575,3900,4225,4550,4875,5200,5525,

Now, get the least common multiple of 320, 325 which is 20800

So, the LCM of 320, 325 is 20800.

Least Common Multiple (LCM) of 320 and 325 with the help of Prime Factorisation

One method for determining the LCM of 320 and 325 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 320's prime factorization:


2 320
2 160
2 80
2 40
2 20
2 10
5 5
1

Prime factors of 320 are 2,5.

320 = 26×51

And this is 325's prime factorization:


5 325
5 65
13 13
1

Prime factors of 325 are 5,13.

325 = 52×131

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: 2,5,13

.

26×52×131 = 20800

This shows that the LCM of 320 and 325 is 20800.

How to Calculate the LCM of 320 and 325 Using Common Multiples

The first step in determining the Least Common Multiple of 320 and 325 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 320 and 325:

Lets look at the first ten multiples of these numbers, 320 and 325:

320,640,960,1280,1600,1920,2240,2560,2880,5440 are the first ten multiples of 320.

325,650,975,1300,1625,1950,2275,2600,2925,5525 are the first ten multiples of 325.

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 320 and 325, for example, are 3840, 5440, and 5200. 20800 is the least common multiple since it is the smallest.

320 and 325 have an LCM of 20800.

Least Common Multiple of 320 and 325 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 320 and 325, than apply into the LCM equation.

GCF(320,325) = 5
LCM(320,325) = ( 320 × 325) / 5
LCM(320,325) = 104000 / 5
LCM(320,325) = 20800
