Given numbers are 381,831,491,187

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

The LCM of 381,831,491,187 is 9690090729.

Find LCM of 381,831,491,187 with Prime Factorization

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

3 x 127 x 277 x 491 x 187 = 9690090729

Therefore, the lowest common multiple of 381,831,491,187 is 9690090729.

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.

381 x 831 x 491 x 187 = 29070272187

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.

381 : 1, 3, 127, 381

831 : 1, 3, 277, 831

491 : 1, 491

187 : 1, 11, 17, 187

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,831,491,187, is 1.

Now, the common factors can be found like this.

381:3x 127

831:3x 277

491:491

187:11x 17

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 = 29070272187/(1x3)

LCM = 29070272187/3

LCM = 9690090729

Thus, we can understand that the LCM of 381,831,491,187 is 9690090729.
