Given numbers are 815,515,894,422

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

The LCM of 815,515,894,422 is 15834881130.

Find LCM of 815,515,894,422 with Prime Factorization

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

2 x 5 x 163 x 103 x 447 x 211 = 15834881130

Therefore, the lowest common multiple of 815,515,894,422 is 15834881130.

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.

815 x 515 x 894 x 422 = 158348811300

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.

815 : 1, 5, 163, 815

515 : 1, 5, 103, 515

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

422 : 1, 2, 211, 422

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,515,894,422, is 1.

Now, the common factors can be found like this.

815:5x 163

515:5x 103

894:2x 3x 149

422:2x 211

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 158348811300/(1x10)

LCM = 158348811300/10

LCM = 15834881130

Thus, we can understand that the LCM of 815,515,894,422 is 15834881130.
