Given numbers are 872,638,786,305,115

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

The LCM of 872,638,786,305,115 is 766879968360.

Find LCM of 872,638,786,305,115 with Prime Factorization

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

2 x 5 x 436 x 319 x 393 x 61 x 23 = 766879968360

Therefore, the lowest common multiple of 872,638,786,305,115 is 766879968360.

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.

872 x 638 x 786 x 305 x 115 = 15337599367200

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.

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

638 : 1, 2, 11, 22, 29, 58, 319, 638

786 : 1, 2, 3, 6, 131, 262, 393, 786

305 : 1, 5, 61, 305

115 : 1, 5, 23, 115

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,638,786,305,115, is 1.

Now, the common factors can be found like this.

872:2x 2x 2x 109

638:2x 11x 29

786:2x 3x 131

305:5x 61

115:5x 23

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 5 = 20

Therefore, the value for common factors is 20.

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 = 15337599367200/(1x20)

LCM = 15337599367200/20

LCM = 766879968360

Thus, we can understand that the LCM of 872,638,786,305,115 is 766879968360.
