Given numbers are 421,432,671,421,809

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

The LCM of 421,432,671,421,809 is 98727214608.

Find LCM of 421,432,671,421,809 with Prime Factorization

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

421 x 1 x 432 x 671 x 1 x 809 = 98727214608

Therefore, the lowest common multiple of 421,432,671,421,809 is 98727214608.

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.

421 x 432 x 671 x 421 x 809 = 41564157349968

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.

421 : 1, 421

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

671 : 1, 11, 61, 671

421 : 1, 421

809 : 1, 809

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,432,671,421,809, is 1.

Now, the common factors can be found like this.

421:421

432:2x 2x 2x 2x 3x 3x 3

671:11x 61

421:421

809:809

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

421 = 421

Therefore, the value for common factors is 421.

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 = 41564157349968/(1x421)

LCM = 41564157349968/421

LCM = 98727214608

Thus, we can understand that the LCM of 421,432,671,421,809 is 98727214608.
