Given numbers are 517,621,321,717

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

The LCM of 517,621,321,717 is 8210390661.

Find LCM of 517,621,321,717 with Prime Factorization

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

3 x 517 x 207 x 107 x 239 = 8210390661

Therefore, the lowest common multiple of 517,621,321,717 is 8210390661.

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.

517 x 621 x 321 x 717 = 73893515949

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.

517 : 1, 11, 47, 517

621 : 1, 3, 9, 23, 27, 69, 207, 621

321 : 1, 3, 107, 321

717 : 1, 3, 239, 717

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,621,321,717, is 1.

Now, the common factors can be found like this.

517:11x 47

621:3x 3x 3x 23

321:3x 107

717:3x 239

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 = 73893515949/(1x9)

LCM = 73893515949/9

LCM = 8210390661

Thus, we can understand that the LCM of 517,621,321,717 is 8210390661.
