Given numbers are 816,676,891,806

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

The LCM of 816,676,891,806 is 1269682128.

Find LCM of 816,676,891,806 with Prime Factorization

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

2 x 2 x 3 x 13 x 68 x 13 x 297 x 31 = 1269682128

Therefore, the lowest common multiple of 816,676,891,806 is 1269682128.

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.

816 x 676 x 891 x 806 = 396140823936

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.

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

806 : 1, 2, 13, 26, 31, 62, 403, 806

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,676,891,806, is 1.

Now, the common factors can be found like this.

816:2x 2x 2x 2x 3x 17

676:2x 2x 13x 13

891:3x 3x 3x 3x 11

806:2x 13x 31

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 13 = 312

Therefore, the value for common factors is 312.

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 = 396140823936/(1x312)

LCM = 396140823936/312

LCM = 1269682128

Thus, we can understand that the LCM of 816,676,891,806 is 1269682128.
