Given numbers are 617,638,667,957

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

The LCM of 617,638,667,957 is 27161574.

Find LCM of 617,638,667,957 with Prime Factorization

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

11 x 29 x 617 x 2 x 23 x 3 = 27161574

Therefore, the lowest common multiple of 617,638,667,957 is 27161574.

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.

617 x 638 x 667 x 957 = 251271721074

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.

617 : 1, 617

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

667 : 1, 23, 29, 667

957 : 1, 3, 11, 29, 33, 87, 319, 957

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,638,667,957, is 1.

Now, the common factors can be found like this.

617:617

638:2x 11x 29

667:23x 29

957:3x 11x 29

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

11x 29x 29 = 9251

Therefore, the value for common factors is 9251.

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 = 251271721074/(1x9251)

LCM = 251271721074/9251

LCM = 27161574

Thus, we can understand that the LCM of 617,638,667,957 is 27161574.
