Given numbers are 121,638,485,605

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

The LCM of 121,638,485,605 is 3403730.

Find LCM of 121,638,485,605 with Prime Factorization

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

5 x 11 x 11 x 1 x 58 x 97 x 1 = 3403730

Therefore, the lowest common multiple of 121,638,485,605 is 3403730.

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.

121 x 638 x 485 x 605 = 22651823150

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.

121 : 1, 11, 121

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

485 : 1, 5, 97, 485

605 : 1, 5, 11, 55, 121, 605

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,638,485,605, is 1.

Now, the common factors can be found like this.

121:11x 11

638:2x 11x 29

485:5x 97

605:5x 11x 11

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

5x 11x 11x 11 = 6655

Therefore, the value for common factors is 6655.

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 = 22651823150/(1x6655)

LCM = 22651823150/6655

LCM = 3403730

Thus, we can understand that the LCM of 121,638,485,605 is 3403730.
