Given numbers are 391,578,731,982,568

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

The LCM of 391,578,731,982,568 is 79712047048.

Find LCM of 391,578,731,982,568 with Prime Factorization

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

2 x 17 x 23 x 17 x 43 x 491 x 284 = 79712047048

Therefore, the lowest common multiple of 391,578,731,982,568 is 79712047048.

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.

391 x 578 x 731 x 982 x 568 = 92147126387488

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.

391 : 1, 17, 23, 391

578 : 1, 2, 17, 34, 289, 578

731 : 1, 17, 43, 731

982 : 1, 2, 491, 982

568 : 1, 2, 4, 8, 71, 142, 284, 568

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,578,731,982,568, is 1.

Now, the common factors can be found like this.

391:17x 23

578:2x 17x 17

731:17x 43

982:2x 491

568:2x 2x 2x 71

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 17x 17 = 1156

Therefore, the value for common factors is 1156.

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 = 92147126387488/(1x1156)

LCM = 92147126387488/1156

LCM = 79712047048

Thus, we can understand that the LCM of 391,578,731,982,568 is 79712047048.
