Given numbers are 660,581,393,894,424

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

The LCM of 660,581,393,894,424 is 793384108440.

Find LCM of 660,581,393,894,424 with Prime Factorization

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

2 x 2 x 3 x 55 x 581 x 131 x 149 x 106 = 793384108440

Therefore, the lowest common multiple of 660,581,393,894,424 is 793384108440.

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.

660 x 581 x 393 x 894 x 424 = 57123655807680

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

581 : 1, 7, 83, 581

393 : 1, 3, 131, 393

894 : 1, 2, 3, 6, 149, 298, 447, 894

424 : 1, 2, 4, 8, 53, 106, 212, 424

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,581,393,894,424, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

581:7x 83

393:3x 131

894:2x 3x 149

424:2x 2x 2x 53

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

2x 2x 2x 3x 3 = 72

Therefore, the value for common factors is 72.

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 = 57123655807680/(1x72)

LCM = 57123655807680/72

LCM = 793384108440

Thus, we can understand that the LCM of 660,581,393,894,424 is 793384108440.
