Given numbers are 381,489,207,653,818

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

The LCM of 381,489,207,653,818 is 2288907044478.

Find LCM of 381,489,207,653,818 with Prime Factorization

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

3 x 127 x 163 x 69 x 653 x 818 = 2288907044478

Therefore, the lowest common multiple of 381,489,207,653,818 is 2288907044478.

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 489 x 207 x 653 x 818 = 20600163400302

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

489 : 1, 3, 163, 489

207 : 1, 3, 9, 23, 69, 207

653 : 1, 653

818 : 1, 2, 409, 818

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,489,207,653,818, is 1.

Now, the common factors can be found like this.

381:3x 127

489:3x 163

207:3x 3x 23

653:653

818:2x 409

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 20600163400302/(1x9)

LCM = 20600163400302/9

LCM = 2288907044478

Thus, we can understand that the LCM of 381,489,207,653,818 is 2288907044478.
