Given numbers are 617,855,815,779,910

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

The LCM of 617,855,815,779,910 is 641643985710.

Find LCM of 617,855,815,779,910 with Prime Factorization

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

5 x 19 x 617 x 9 x 163 x 41 x 182 = 641643985710

Therefore, the lowest common multiple of 617,855,815,779,910 is 641643985710.

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.

617 x 855 x 815 x 779 x 910 = 304780893212250

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.

617 : 1, 617

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

815 : 1, 5, 163, 815

779 : 1, 19, 41, 779

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,855,815,779,910, is 1.

Now, the common factors can be found like this.

617:617

855:3x 3x 5x 19

815:5x 163

779:19x 41

910:2x 5x 7x 13

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

5x 5x 19 = 475

Therefore, the value for common factors is 475.

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 = 304780893212250/(1x475)

LCM = 304780893212250/475

LCM = 641643985710

Thus, we can understand that the LCM of 617,855,815,779,910 is 641643985710.
