Given numbers are 581,457,646,790

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

The LCM of 581,457,646,790 is 67751972890.

Find LCM of 581,457,646,790 with Prime Factorization

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

2 x 581 x 457 x 323 x 395 = 67751972890

Therefore, the lowest common multiple of 581,457,646,790 is 67751972890.

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.

581 x 457 x 646 x 790 = 135503945780

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.

581 : 1, 7, 83, 581

457 : 1, 457

646 : 1, 2, 17, 19, 34, 38, 323, 646

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 581,457,646,790, is 1.

Now, the common factors can be found like this.

581:7x 83

457:457

646:2x 17x 19

790:2x 5x 79

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

2 = 2

Therefore, the value for common factors is 2.

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 = 135503945780/(1x2)

LCM = 135503945780/2

LCM = 67751972890

Thus, we can understand that the LCM of 581,457,646,790 is 67751972890.
