Given numbers are 811,731,661,811

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

The LCM of 811,731,661,811 is 391867901.

Find LCM of 811,731,661,811 with Prime Factorization

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

811 x 1 x 731 x 661 x 1 = 391867901

Therefore, the lowest common multiple of 811,731,661,811 is 391867901.

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 731 x 661 x 811 = 317804867711

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

731 : 1, 17, 43, 731

661 : 1, 661

811 : 1, 811

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,731,661,811, is 1.

Now, the common factors can be found like this.

811:811

731:17x 43

661:661

811:811

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

811 = 811

Therefore, the value for common factors is 811.

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 = 317804867711/(1x811)

LCM = 317804867711/811

LCM = 391867901

Thus, we can understand that the LCM of 811,731,661,811 is 391867901.
