Given numbers are 631,617,581,664

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

The LCM of 631,617,581,664 is 1809591896.

Find LCM of 631,617,581,664 with Prime Factorization

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

83 x 631 x 617 x 7 x 8 = 1809591896

Therefore, the lowest common multiple of 631,617,581,664 is 1809591896.

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.

631 x 617 x 581 x 664 = 150196127368

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.

631 : 1, 631

617 : 1, 617

581 : 1, 7, 83, 581

664 : 1, 2, 4, 8, 83, 166, 332, 664

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,617,581,664, is 1.

Now, the common factors can be found like this.

631:631

617:617

581:7x 83

664:2x 2x 2x 83

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

83 = 83

Therefore, the value for common factors is 83.

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 = 150196127368/(1x83)

LCM = 150196127368/83

LCM = 1809591896

Thus, we can understand that the LCM of 631,617,581,664 is 1809591896.
