Given numbers are 476,866,394,394,643

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

The LCM of 476,866,394,394,643 is 26107906468.

Find LCM of 476,866,394,394,643 with Prime Factorization

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

2 x 197 x 238 x 433 x 1 x 1 x 643 = 26107906468

Therefore, the lowest common multiple of 476,866,394,394,643 is 26107906468.

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.

476 x 866 x 394 x 394 x 643 = 41146060593568

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.

476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476

866 : 1, 2, 433, 866

394 : 1, 2, 197, 394

394 : 1, 2, 197, 394

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,866,394,394,643, is 1.

Now, the common factors can be found like this.

476:2x 2x 7x 17

866:2x 433

394:2x 197

394:2x 197

643:643

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 197 = 1576

Therefore, the value for common factors is 1576.

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 = 41146060593568/(1x1576)

LCM = 41146060593568/1576

LCM = 26107906468

Thus, we can understand that the LCM of 476,866,394,394,643 is 26107906468.
