Given numbers are 617,209,821,407

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

The LCM of 617,209,821,407 is 3917205281.

Find LCM of 617,209,821,407 with Prime Factorization

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

11 x 617 x 19 x 821 x 37 = 3917205281

Therefore, the lowest common multiple of 617,209,821,407 is 3917205281.

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 209 x 821 x 407 = 43089258091

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

209 : 1, 11, 19, 209

821 : 1, 821

407 : 1, 11, 37, 407

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,209,821,407, is 1.

Now, the common factors can be found like this.

617:617

209:11x 19

821:821

407:11x 37

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

11 = 11

Therefore, the value for common factors is 11.

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 = 43089258091/(1x11)

LCM = 43089258091/11

LCM = 3917205281

Thus, we can understand that the LCM of 617,209,821,407 is 3917205281.
