Given numbers are 395,344,685,19

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

The LCM of 395,344,685,19 is 353695640.

Find LCM of 395,344,685,19 with Prime Factorization

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

5 x 79 x 344 x 137 x 19 = 353695640

Therefore, the lowest common multiple of 395,344,685,19 is 353695640.

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 344 x 685 x 19 = 1768478200

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

344 : 1, 2, 4, 8, 43, 86, 172, 344

685 : 1, 5, 137, 685

19 : 1, 19

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 395,344,685,19, is 1.

Now, the common factors can be found like this.

395:5x 79

344:2x 2x 2x 43

685:5x 137

19:19

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 = 1768478200/(1x5)

LCM = 1768478200/5

LCM = 353695640

Thus, we can understand that the LCM of 395,344,685,19 is 353695640.
