Given numbers are 780,439,388,585

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

The LCM of 780,439,388,585 is 99644220.

Find LCM of 780,439,388,585 with Prime Factorization

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

2 x 2 x 3 x 5 x 13 x 1 x 439 x 97 x 3 = 99644220

Therefore, the lowest common multiple of 780,439,388,585 is 99644220.

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 439 x 388 x 585 = 77722491600

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

439 : 1, 439

388 : 1, 2, 4, 97, 194, 388

585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,439,388,585, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

439:439

388:2x 2x 97

585:3x 3x 5x 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 2x 3x 5x 13 = 780

Therefore, the value for common factors is 780.

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 = 77722491600/(1x780)

LCM = 77722491600/780

LCM = 99644220

Thus, we can understand that the LCM of 780,439,388,585 is 99644220.
