Given numbers are 581,638,631,354

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

The LCM of 581,638,631,354 is 41399913786.

Find LCM of 581,638,631,354 with Prime Factorization

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

2 x 581 x 319 x 631 x 177 = 41399913786

Therefore, the lowest common multiple of 581,638,631,354 is 41399913786.

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 638 x 631 x 354 = 82799827572

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

638 : 1, 2, 11, 22, 29, 58, 319, 638

631 : 1, 631

354 : 1, 2, 3, 6, 59, 118, 177, 354

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 581,638,631,354, is 1.

Now, the common factors can be found like this.

581:7x 83

638:2x 11x 29

631:631

354:2x 3x 59

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 = 82799827572/(1x2)

LCM = 82799827572/2

LCM = 41399913786

Thus, we can understand that the LCM of 581,638,631,354 is 41399913786.
