Given numbers are 811,717,780,663

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

The LCM of 811,717,780,663 is 2570172540.

Find LCM of 811,717,780,663 with Prime Factorization

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

3 x 13 x 811 x 239 x 20 x 17 = 2570172540

Therefore, the lowest common multiple of 811,717,780,663 is 2570172540.

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.

811 x 717 x 780 x 663 = 300710187180

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.

811 : 1, 811

717 : 1, 3, 239, 717

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

663 : 1, 3, 13, 17, 39, 51, 221, 663

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,717,780,663, is 1.

Now, the common factors can be found like this.

811:811

717:3x 239

780:2x 2x 3x 5x 13

663:3x 13x 17

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

3x 3x 13 = 117

Therefore, the value for common factors is 117.

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 = 300710187180/(1x117)

LCM = 300710187180/117

LCM = 2570172540

Thus, we can understand that the LCM of 811,717,780,663 is 2570172540.
