Given numbers are 320,514,394,395

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 320,514,394,395 is 1279901120.

Find LCM of 320,514,394,395 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 5 x 32 x 257 x 197 x 79 = 1279901120

Therefore, the lowest common multiple of 320,514,394,395 is 1279901120.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

320 x 514 x 394 x 395 = 25598022400

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

514 : 1, 2, 257, 514

394 : 1, 2, 197, 394

395 : 1, 5, 79, 395

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 320,514,394,395, is 1.

Now, the common factors can be found like this.

320:2x 2x 2x 2x 2x 2x 5

514:2x 257

394:2x 197

395:5x 79

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 5 = 20

Therefore, the value for common factors is 20.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 25598022400/(1x20)

LCM = 25598022400/20

LCM = 1279901120

Thus, we can understand that the LCM of 320,514,394,395 is 1279901120.
