Given numbers are 811,922,811,645

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

The LCM of 811,922,811,645 is 482293590.

Find LCM of 811,922,811,645 with Prime Factorization

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

811 x 1 x 922 x 1 x 645 = 482293590

Therefore, the lowest common multiple of 811,922,811,645 is 482293590.

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 922 x 811 x 645 = 391140101490

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

922 : 1, 2, 461, 922

811 : 1, 811

645 : 1, 3, 5, 15, 43, 129, 215, 645

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,922,811,645, is 1.

Now, the common factors can be found like this.

811:811

922:2x 461

811:811

645:3x 5x 43

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 = 391140101490/(1x811)

LCM = 391140101490/811

LCM = 482293590

Thus, we can understand that the LCM of 811,922,811,645 is 482293590.
