Given numbers are 393,207,581,455,872

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

The LCM of 393,207,581,455,872 is 892992096360.

Find LCM of 393,207,581,455,872 with Prime Factorization

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

3 x 7 x 131 x 69 x 83 x 65 x 872 = 892992096360

Therefore, the lowest common multiple of 393,207,581,455,872 is 892992096360.

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.

393 x 207 x 581 x 455 x 872 = 18752834023560

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.

393 : 1, 3, 131, 393

207 : 1, 3, 9, 23, 69, 207

581 : 1, 7, 83, 581

455 : 1, 5, 7, 13, 35, 65, 91, 455

872 : 1, 2, 4, 8, 109, 218, 436, 872

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,207,581,455,872, is 1.

Now, the common factors can be found like this.

393:3x 131

207:3x 3x 23

581:7x 83

455:5x 7x 13

872:2x 2x 2x 109

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 18752834023560/(1x21)

LCM = 18752834023560/21

LCM = 892992096360

Thus, we can understand that the LCM of 393,207,581,455,872 is 892992096360.
