Given numbers are 810,642,894,180

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

The LCM of 810,642,894,180 is 25827660.

Find LCM of 810,642,894,180 with Prime Factorization

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

2 x 3 x 3 x 5 x 9 x 107 x 149 x 2 = 25827660

Therefore, the lowest common multiple of 810,642,894,180 is 25827660.

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 642 x 894 x 180 = 83681618400

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

642 : 1, 2, 3, 6, 107, 214, 321, 642

894 : 1, 2, 3, 6, 149, 298, 447, 894

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

6 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,642,894,180, is 6.

Now, the common factors can be found like this.

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

642:2x 3x 107

894:2x 3x 149

180:2x 2x 3x 3x 5

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 3x 3x 3x 5 = 540

Therefore, the value for common factors is 540.

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 = 83681618400/(6x540)

LCM = 83681618400/3240

LCM = 25827660

Thus, we can understand that the LCM of 810,642,894,180 is 25827660.
