Given numbers are 128,436,572,431

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

The LCM of 128,436,572,431 is 859903616.

Find LCM of 128,436,572,431 with Prime Factorization

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

2 x 2 x 32 x 109 x 143 x 431 = 859903616

Therefore, the lowest common multiple of 128,436,572,431 is 859903616.

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.

128 x 436 x 572 x 431 = 13758457856

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.

128 : 1, 2, 4, 8, 16, 32, 64, 128

436 : 1, 2, 4, 109, 218, 436

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

431 : 1, 431

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,436,572,431, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

436:2x 2x 109

572:2x 2x 11x 13

431:431

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 2 = 16

Therefore, the value for common factors is 16.

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 = 13758457856/(1x16)

LCM = 13758457856/16

LCM = 859903616

Thus, we can understand that the LCM of 128,436,572,431 is 859903616.
