Given Numbers are 316, 320

We can find the LCM of 316, 320 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 316 and 320

Multiples of 316 =316,632,948,1264,1580,1896,2212,2528,2844,3160,3476,3792,4108,4424,4740,5056,5372,

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

Now, get the least common multiple of 316, 320 which is 25280

So, the LCM of 316, 320 is 25280.

One method for determining the LCM of 316 and 320 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 316's prime factorization:

Prime factors of 316 are 2,79.

316 = 2²×79¹

And this is 320's prime factorization:

Prime factors of 320 are 2,5.

320 = 2⁶×5¹

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: 2,79,5

2⁶×5¹×79¹ = 25280

This shows that the LCM of 316 and 320 is 25280.

The first step in determining the Least Common Multiple of 316 and 320 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 316 and 320:

Lets look at the first ten multiples of these numbers, 316 and 320:

316,632,948,1264,1580,1896,2212,2528,2844,5372 are the first ten multiples of 316.

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

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 316 and 320, for example, are 3792, 5372, and 5120. 25280 is the least common multiple since it is the smallest.

316 and 320 have an LCM of 25280.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 316 and 320, than apply into the LCM equation.

GCF(316,320) = 4
LCM(316,320) = ( 316 × 320) / 4
LCM(316,320) = 101120 / 4
LCM(316,320) = 25280
