Given numbers are 816,811,921,809

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

The LCM of 816,811,921,809 is 164360672688.

Find LCM of 816,811,921,809 with Prime Factorization

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

3 x 272 x 811 x 307 x 809 = 164360672688

Therefore, the lowest common multiple of 816,811,921,809 is 164360672688.

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 811 x 921 x 809 = 493082018064

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

811 : 1, 811

921 : 1, 3, 307, 921

809 : 1, 809

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,811,921,809, is 1.

Now, the common factors can be found like this.

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

811:811

921:3x 307

809:809

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

3 = 3

Therefore, the value for common factors is 3.

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 = 493082018064/(1x3)

LCM = 493082018064/3

LCM = 164360672688

Thus, we can understand that the LCM of 816,811,921,809 is 164360672688.
