Given numbers are 381,635,581,617

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

The LCM of 381,635,581,617 is 682898685.

Find LCM of 381,635,581,617 with Prime Factorization

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

127 x 3 x 5 x 581 x 617 = 682898685

Therefore, the lowest common multiple of 381,635,581,617 is 682898685.

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.

381 x 635 x 581 x 617 = 86728132995

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.

381 : 1, 3, 127, 381

635 : 1, 5, 127, 635

581 : 1, 7, 83, 581

617 : 1, 617

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,635,581,617, is 1.

Now, the common factors can be found like this.

381:3x 127

635:5x 127

581:7x 83

617:617

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

127 = 127

Therefore, the value for common factors is 127.

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 = 86728132995/(1x127)

LCM = 86728132995/127

LCM = 682898685

Thus, we can understand that the LCM of 381,635,581,617 is 682898685.
