Given numbers are 808,530,445,421

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

The LCM of 808,530,445,421 is 8022862280.

Find LCM of 808,530,445,421 with Prime Factorization

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

2 x 5 x 404 x 53 x 89 x 421 = 8022862280

Therefore, the lowest common multiple of 808,530,445,421 is 8022862280.

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.

808 x 530 x 445 x 421 = 80228622800

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.

808 : 1, 2, 4, 8, 101, 202, 404, 808

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

445 : 1, 5, 89, 445

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,530,445,421, is 1.

Now, the common factors can be found like this.

808:2x 2x 2x 101

530:2x 5x 53

445:5x 89

421:421

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 80228622800/(1x10)

LCM = 80228622800/10

LCM = 8022862280

Thus, we can understand that the LCM of 808,530,445,421 is 8022862280.
