Given numbers are 405,996,115,894,920

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

The LCM of 405,996,115,894,920 is 921588840.

Find LCM of 405,996,115,894,920 with Prime Factorization

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

2 x 2 x 3 x 5 x 23 x 27 x 83 x 1 x 149 x 2 = 921588840

Therefore, the lowest common multiple of 405,996,115,894,920 is 921588840.

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.

405 x 996 x 115 x 894 x 920 = 38153777976000

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.

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996

115 : 1, 5, 23, 115

894 : 1, 2, 3, 6, 149, 298, 447, 894

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,996,115,894,920, is 1.

Now, the common factors can be found like this.

405:3x 3x 3x 3x 5

996:2x 2x 3x 83

115:5x 23

894:2x 3x 149

920:2x 2x 2x 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 2x 3x 3x 5x 5x 23 = 41400

Therefore, the value for common factors is 41400.

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 = 38153777976000/(1x41400)

LCM = 38153777976000/41400

LCM = 921588840

Thus, we can understand that the LCM of 405,996,115,894,920 is 921588840.
