Given numbers are 605,555,388,530,420

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

The LCM of 605,555,388,530,420 is 9666827940.

Find LCM of 605,555,388,530,420 with Prime Factorization

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

2 x 2 x 3 x 5 x 121 x 37 x 97 x 53 x 7 = 9666827940

Therefore, the lowest common multiple of 605,555,388,530,420 is 9666827940.

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.

605 x 555 x 388 x 530 x 420 = 29000483820000

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.

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

555 : 1, 3, 5, 15, 37, 111, 185, 555

388 : 1, 2, 4, 97, 194, 388

530 : 1, 2, 5, 10, 53, 106, 265, 530

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,555,388,530,420, is 1.

Now, the common factors can be found like this.

605:5x 11x 11

555:3x 5x 37

388:2x 2x 97

530:2x 5x 53

420:2x 2x 3x 5x 7

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 3x 5x 5x 5 = 3000

Therefore, the value for common factors is 3000.

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 = 29000483820000/(1x3000)

LCM = 29000483820000/3000

LCM = 9666827940

Thus, we can understand that the LCM of 605,555,388,530,420 is 9666827940.
