Given numbers are 860,780,515,291,105

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

The LCM of 860,780,515,291,105 is 2345686980.

Find LCM of 860,780,515,291,105 with Prime Factorization

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

2 x 2 x 3 x 5 x 43 x 13 x 103 x 97 x 7 = 2345686980

Therefore, the lowest common multiple of 860,780,515,291,105 is 2345686980.

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.

860 x 780 x 515 x 291 x 105 = 10555591410000

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.

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

515 : 1, 5, 103, 515

291 : 1, 3, 97, 291

105 : 1, 3, 5, 7, 15, 21, 35, 105

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,780,515,291,105, is 1.

Now, the common factors can be found like this.

860:2x 2x 5x 43

780:2x 2x 3x 5x 13

515:5x 103

291:3x 97

105:3x 5x 7

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 3x 3x 5x 5x 5 = 4500

Therefore, the value for common factors is 4500.

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 = 10555591410000/(1x4500)

LCM = 10555591410000/4500

LCM = 2345686980

Thus, we can understand that the LCM of 860,780,515,291,105 is 2345686980.
