Given numbers are 810,646,316,547

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

The LCM of 810,646,316,547 is 22611634380.

Find LCM of 810,646,316,547 with Prime Factorization

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

2 x 405 x 323 x 158 x 547 = 22611634380

Therefore, the lowest common multiple of 810,646,316,547 is 22611634380.

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.

810 x 646 x 316 x 547 = 90446537520

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.

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

646 : 1, 2, 17, 19, 34, 38, 323, 646

316 : 1, 2, 4, 79, 158, 316

547 : 1, 547

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,646,316,547, is 1.

Now, the common factors can be found like this.

810:2x 3x 3x 3x 3x 5

646:2x 17x 19

316:2x 2x 79

547:547

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 90446537520/(1x4)

LCM = 90446537520/4

LCM = 22611634380

Thus, we can understand that the LCM of 810,646,316,547 is 22611634380.
