Given numbers are 478,900,655,781,730

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

The LCM of 478,900,655,781,730 is 1606518015300.

Find LCM of 478,900,655,781,730 with Prime Factorization

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

2 x 5 x 239 x 90 x 131 x 781 x 73 = 1606518015300

Therefore, the lowest common multiple of 478,900,655,781,730 is 1606518015300.

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.

478 x 900 x 655 x 781 x 730 = 160651801530000

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.

478 : 1, 2, 239, 478

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

655 : 1, 5, 131, 655

781 : 1, 11, 71, 781

730 : 1, 2, 5, 10, 73, 146, 365, 730

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,900,655,781,730, is 1.

Now, the common factors can be found like this.

478:2x 239

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

655:5x 131

781:11x 71

730:2x 5x 73

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 5x 5 = 100

Therefore, the value for common factors is 100.

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 = 160651801530000/(1x100)

LCM = 160651801530000/100

LCM = 1606518015300

Thus, we can understand that the LCM of 478,900,655,781,730 is 1606518015300.
