Given numbers are 680,579,406,545

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

The LCM of 680,579,406,545 is 8711842440.

Find LCM of 680,579,406,545 with Prime Factorization

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

2 x 5 x 68 x 579 x 203 x 109 = 8711842440

Therefore, the lowest common multiple of 680,579,406,545 is 8711842440.

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.

680 x 579 x 406 x 545 = 87118424400

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.

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

579 : 1, 3, 193, 579

406 : 1, 2, 7, 14, 29, 58, 203, 406

545 : 1, 5, 109, 545

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,579,406,545, is 1.

Now, the common factors can be found like this.

680:2x 2x 2x 5x 17

579:3x 193

406:2x 7x 29

545:5x 109

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 = 87118424400/(1x10)

LCM = 87118424400/10

LCM = 8711842440

Thus, we can understand that the LCM of 680,579,406,545 is 8711842440.
