Given numbers are 717,810,409,399,631

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

The LCM of 717,810,409,399,631 is 6644881310130.

Find LCM of 717,810,409,399,631 with Prime Factorization

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

3 x 239 x 270 x 409 x 133 x 631 = 6644881310130

Therefore, the lowest common multiple of 717,810,409,399,631 is 6644881310130.

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.

717 x 810 x 409 x 399 x 631 = 59803931791170

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.

717 : 1, 3, 239, 717

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

409 : 1, 409

399 : 1, 3, 7, 19, 21, 57, 133, 399

631 : 1, 631

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,810,409,399,631, is 1.

Now, the common factors can be found like this.

717:3x 239

810:2x 3x 3x 3x 3x 5

409:409

399:3x 7x 19

631:631

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 59803931791170/(1x9)

LCM = 59803931791170/9

LCM = 6644881310130

Thus, we can understand that the LCM of 717,810,409,399,631 is 6644881310130.
