Given numbers are 643,900,539,605,286

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

The LCM of 643,900,539,605,286 is 44604459900.

Find LCM of 643,900,539,605,286 with Prime Factorization

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

2 x 5 x 11 x 643 x 90 x 49 x 11 x 13 = 44604459900

Therefore, the lowest common multiple of 643,900,539,605,286 is 44604459900.

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.

643 x 900 x 539 x 605 x 286 = 53971396479000

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.

643 : 1, 643

900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900

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

605 : 1, 5, 11, 55, 121, 605

286 : 1, 2, 11, 13, 22, 26, 143, 286

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,900,539,605,286, is 1.

Now, the common factors can be found like this.

643:643

900:2x 2x 3x 3x 5x 5

539:7x 7x 11

605:5x 11x 11

286:2x 11x 13

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

2x 5x 11x 11 = 1210

Therefore, the value for common factors is 1210.

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 = 53971396479000/(1x1210)

LCM = 53971396479000/1210

LCM = 44604459900

Thus, we can understand that the LCM of 643,900,539,605,286 is 44604459900.
