Given numbers are 643,605,185,518,115

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

The LCM of 643,605,185,518,115 is 4634724710.

Find LCM of 643,605,185,518,115 with Prime Factorization

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

5 x 37 x 643 x 121 x 1 x 14 x 23 = 4634724710

Therefore, the lowest common multiple of 643,605,185,518,115 is 4634724710.

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 605 x 185 x 518 x 115 = 4287120356750

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

605 : 1, 5, 11, 55, 121, 605

185 : 1, 5, 37, 185

518 : 1, 2, 7, 14, 37, 74, 259, 518

115 : 1, 5, 23, 115

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,605,185,518,115, is 1.

Now, the common factors can be found like this.

643:643

605:5x 11x 11

185:5x 37

518:2x 7x 37

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.

5x 5x 37 = 925

Therefore, the value for common factors is 925.

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 = 4287120356750/(1x925)

LCM = 4287120356750/925

LCM = 4634724710

Thus, we can understand that the LCM of 643,605,185,518,115 is 4634724710.
