Given numbers are 815,857,668,730

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

The LCM of 815,857,668,730 is 34059459620.

Find LCM of 815,857,668,730 with Prime Factorization

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

2 x 5 x 163 x 857 x 334 x 73 = 34059459620

Therefore, the lowest common multiple of 815,857,668,730 is 34059459620.

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.

815 x 857 x 668 x 730 = 340594596200

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.

815 : 1, 5, 163, 815

857 : 1, 857

668 : 1, 2, 4, 167, 334, 668

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 815,857,668,730, is 1.

Now, the common factors can be found like this.

815:5x 163

857:857

668:2x 2x 167

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 = 340594596200/(1x10)

LCM = 340594596200/10

LCM = 34059459620

Thus, we can understand that the LCM of 815,857,668,730 is 34059459620.
