Given numbers are 638,591,993,634

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

The LCM of 638,591,993,634 is 39563564766.

Find LCM of 638,591,993,634 with Prime Factorization

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

2 x 3 x 319 x 197 x 331 x 317 = 39563564766

Therefore, the lowest common multiple of 638,591,993,634 is 39563564766.

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 591 x 993 x 634 = 237381388596

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

591 : 1, 3, 197, 591

993 : 1, 3, 331, 993

634 : 1, 2, 317, 634

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,591,993,634, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

591:3x 197

993:3x 331

634:2x 317

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 237381388596/(1x6)

LCM = 237381388596/6

LCM = 39563564766

Thus, we can understand that the LCM of 638,591,993,634 is 39563564766.
