Given numbers are 780,539,758,928,398

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

The LCM of 780,539,758,928,398 is 7356371262240.

Find LCM of 780,539,758,928,398 with Prime Factorization

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

2 x 2 x 195 x 539 x 379 x 232 x 199 = 7356371262240

Therefore, the lowest common multiple of 780,539,758,928,398 is 7356371262240.

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.

780 x 539 x 758 x 928 x 398 = 117701940195840

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.

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

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

758 : 1, 2, 379, 758

928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928

398 : 1, 2, 199, 398

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,539,758,928,398, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

539:7x 7x 11

758:2x 379

928:2x 2x 2x 2x 2x 29

398:2x 199

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 2 = 16

Therefore, the value for common factors is 16.

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 = 117701940195840/(1x16)

LCM = 117701940195840/16

LCM = 7356371262240

Thus, we can understand that the LCM of 780,539,758,928,398 is 7356371262240.
