Given numbers are 815,311,831,395

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

The LCM of 815,311,831,395 is 16639723785.

Find LCM of 815,311,831,395 with Prime Factorization

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

5 x 163 x 311 x 831 x 79 = 16639723785

Therefore, the lowest common multiple of 815,311,831,395 is 16639723785.

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 311 x 831 x 395 = 83198618925

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

311 : 1, 311

831 : 1, 3, 277, 831

395 : 1, 5, 79, 395

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,311,831,395, is 1.

Now, the common factors can be found like this.

815:5x 163

311:311

831:3x 277

395:5x 79

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

5 = 5

Therefore, the value for common factors is 5.

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 = 83198618925/(1x5)

LCM = 83198618925/5

LCM = 16639723785

Thus, we can understand that the LCM of 815,311,831,395 is 16639723785.
