Given numbers are 394,806,580,864

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

The LCM of 394,806,580,864 is 9946104480.

Find LCM of 394,806,580,864 with Prime Factorization

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

2 x 2 x 197 x 403 x 145 x 216 = 9946104480

Therefore, the lowest common multiple of 394,806,580,864 is 9946104480.

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.

394 x 806 x 580 x 864 = 159137671680

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.

394 : 1, 2, 197, 394

806 : 1, 2, 13, 26, 31, 62, 403, 806

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,806,580,864, is 2.

Now, the common factors can be found like this.

394:2x 197

806:2x 13x 31

580:2x 2x 5x 29

864:2x 2x 2x 2x 2x 3x 3x 3

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 2 = 8

Therefore, the value for common factors is 8.

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 = 159137671680/(2x8)

LCM = 159137671680/16

LCM = 9946104480

Thus, we can understand that the LCM of 394,806,580,864 is 9946104480.
