Given numbers are 643,287,779,779,382

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

The LCM of 643,287,779,779,382 is 1339398578.

Find LCM of 643,287,779,779,382 with Prime Factorization

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

19 x 41 x 643 x 7 x 1 x 1 x 382 = 1339398578

Therefore, the lowest common multiple of 643,287,779,779,382 is 1339398578.

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.

643 x 287 x 779 x 779 x 382 = 42779051182742

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.

643 : 1, 643

287 : 1, 7, 41, 287

779 : 1, 19, 41, 779

779 : 1, 19, 41, 779

382 : 1, 2, 191, 382

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,287,779,779,382, is 1.

Now, the common factors can be found like this.

643:643

287:7x 41

779:19x 41

779:19x 41

382:2x 191

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

19x 41x 41 = 31939

Therefore, the value for common factors is 31939.

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 = 42779051182742/(1x31939)

LCM = 42779051182742/31939

LCM = 1339398578

Thus, we can understand that the LCM of 643,287,779,779,382 is 1339398578.
