Given numbers are 790,872,731,642

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

The LCM of 790,872,731,642 is 80823190440.

Find LCM of 790,872,731,642 with Prime Factorization

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

2 x 395 x 436 x 731 x 321 = 80823190440

Therefore, the lowest common multiple of 790,872,731,642 is 80823190440.

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.

790 x 872 x 731 x 642 = 323292761760

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.

790 : 1, 2, 5, 10, 79, 158, 395, 790

872 : 1, 2, 4, 8, 109, 218, 436, 872

731 : 1, 17, 43, 731

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,872,731,642, is 1.

Now, the common factors can be found like this.

790:2x 5x 79

872:2x 2x 2x 109

731:17x 43

642:2x 3x 107

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 323292761760/(1x4)

LCM = 323292761760/4

LCM = 80823190440

Thus, we can understand that the LCM of 790,872,731,642 is 80823190440.
