Given numbers are 842,638,358,358,395

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

The LCM of 842,638,358,358,395 is 18991221590.

Find LCM of 842,638,358,358,395 with Prime Factorization

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

2 x 179 x 421 x 319 x 1 x 1 x 395 = 18991221590

Therefore, the lowest common multiple of 842,638,358,358,395 is 18991221590.

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.

842 x 638 x 358 x 358 x 395 = 27195429316880

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.

842 : 1, 2, 421, 842

638 : 1, 2, 11, 22, 29, 58, 319, 638

358 : 1, 2, 179, 358

358 : 1, 2, 179, 358

395 : 1, 5, 79, 395

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,638,358,358,395, is 1.

Now, the common factors can be found like this.

842:2x 421

638:2x 11x 29

358:2x 179

358:2x 179

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 2x 179 = 1432

Therefore, the value for common factors is 1432.

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 = 27195429316880/(1x1432)

LCM = 27195429316880/1432

LCM = 18991221590

Thus, we can understand that the LCM of 842,638,358,358,395 is 18991221590.
