Given numbers are 861,179,872,205,617

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

The LCM of 861,179,872,205,617 is 414598604280.

Find LCM of 861,179,872,205,617 with Prime Factorization

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

41 x 21 x 179 x 872 x 5 x 617 = 414598604280

Therefore, the lowest common multiple of 861,179,872,205,617 is 414598604280.

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.

861 x 179 x 872 x 205 x 617 = 16998542775480

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

179 : 1, 179

872 : 1, 2, 4, 8, 109, 218, 436, 872

205 : 1, 5, 41, 205

617 : 1, 617

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,179,872,205,617, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

179:179

872:2x 2x 2x 109

205:5x 41

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.

41 = 41

Therefore, the value for common factors is 41.

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 = 16998542775480/(1x41)

LCM = 16998542775480/41

LCM = 414598604280

Thus, we can understand that the LCM of 861,179,872,205,617 is 414598604280.
