Given numbers are 638,417,539,377

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

The LCM of 638,417,539,377 is 169471302.

Find LCM of 638,417,539,377 with Prime Factorization

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

11 x 29 x 2 x 417 x 49 x 13 = 169471302

Therefore, the lowest common multiple of 638,417,539,377 is 169471302.

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.

638 x 417 x 539 x 377 = 54061345338

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.

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

417 : 1, 3, 139, 417

539 : 1, 7, 11, 49, 77, 539

377 : 1, 13, 29, 377

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,417,539,377, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

417:3x 139

539:7x 7x 11

377:13x 29

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

11x 29 = 319

Therefore, the value for common factors is 319.

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 = 54061345338/(1x319)

LCM = 54061345338/319

LCM = 169471302

Thus, we can understand that the LCM of 638,417,539,377 is 169471302.
