Given numbers are 686,415,617,391,730

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

The LCM of 686,415,617,391,730 is 5013684415390.

Find LCM of 686,415,617,391,730 with Prime Factorization

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

2 x 5 x 343 x 83 x 617 x 391 x 73 = 5013684415390

Therefore, the lowest common multiple of 686,415,617,391,730 is 5013684415390.

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.

686 x 415 x 617 x 391 x 730 = 50136844153900

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.

686 : 1, 2, 7, 14, 49, 98, 343, 686

415 : 1, 5, 83, 415

617 : 1, 617

391 : 1, 17, 23, 391

730 : 1, 2, 5, 10, 73, 146, 365, 730

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,415,617,391,730, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

415:5x 83

617:617

391:17x 23

730:2x 5x 73

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 50136844153900/(1x10)

LCM = 50136844153900/10

LCM = 5013684415390

Thus, we can understand that the LCM of 686,415,617,391,730 is 5013684415390.
