Given numbers are 381,194,810,391,806

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

The LCM of 381,194,810,391,806 is 1572324847470.

Find LCM of 381,194,810,391,806 with Prime Factorization

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

2 x 3 x 127 x 97 x 135 x 391 x 403 = 1572324847470

Therefore, the lowest common multiple of 381,194,810,391,806 is 1572324847470.

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.

381 x 194 x 810 x 391 x 806 = 18867898169640

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.

381 : 1, 3, 127, 381

194 : 1, 2, 97, 194

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

391 : 1, 17, 23, 391

806 : 1, 2, 13, 26, 31, 62, 403, 806

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,194,810,391,806, is 1.

Now, the common factors can be found like this.

381:3x 127

194:2x 97

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

391:17x 23

806:2x 13x 31

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 3 = 12

Therefore, the value for common factors is 12.

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 = 18867898169640/(1x12)

LCM = 18867898169640/12

LCM = 1572324847470

Thus, we can understand that the LCM of 381,194,810,391,806 is 1572324847470.
