Given numbers are 668,115,563,487,390

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

The LCM of 668,115,563,487,390 is 821440792380.

Find LCM of 668,115,563,487,390 with Prime Factorization

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

2 x 5 x 334 x 23 x 563 x 487 x 39 = 821440792380

Therefore, the lowest common multiple of 668,115,563,487,390 is 821440792380.

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.

668 x 115 x 563 x 487 x 390 = 8214407923800

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.

668 : 1, 2, 4, 167, 334, 668

115 : 1, 5, 23, 115

563 : 1, 563

487 : 1, 487

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,115,563,487,390, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

115:5x 23

563:563

487:487

390:2x 3x 5x 13

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 8214407923800/(1x10)

LCM = 8214407923800/10

LCM = 821440792380

Thus, we can understand that the LCM of 668,115,563,487,390 is 821440792380.
