Given numbers are 819,219,638,115

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

The LCM of 819,219,638,115 is 4386572190.

Find LCM of 819,219,638,115 with Prime Factorization

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

3 x 273 x 73 x 638 x 115 = 4386572190

Therefore, the lowest common multiple of 819,219,638,115 is 4386572190.

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.

819 x 219 x 638 x 115 = 13159716570

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.

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

219 : 1, 3, 73, 219

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

115 : 1, 5, 23, 115

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,219,638,115, is 1.

Now, the common factors can be found like this.

819:3x 3x 7x 13

219:3x 73

638:2x 11x 29

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.

3 = 3

Therefore, the value for common factors is 3.

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 = 13159716570/(1x3)

LCM = 13159716570/3

LCM = 4386572190

Thus, we can understand that the LCM of 819,219,638,115 is 4386572190.
