Given numbers are 395,631,515,815

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

The LCM of 395,631,515,815 is 4184574305.

Find LCM of 395,631,515,815 with Prime Factorization

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

5 x 79 x 631 x 103 x 163 = 4184574305

Therefore, the lowest common multiple of 395,631,515,815 is 4184574305.

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.

395 x 631 x 515 x 815 = 104614357625

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.

395 : 1, 5, 79, 395

631 : 1, 631

515 : 1, 5, 103, 515

815 : 1, 5, 163, 815

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 395,631,515,815, is 1.

Now, the common factors can be found like this.

395:5x 79

631:631

515:5x 103

815:5x 163

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 104614357625/(1x25)

LCM = 104614357625/25

LCM = 4184574305

Thus, we can understand that the LCM of 395,631,515,815 is 4184574305.
