Given numbers are 391,304,190,494

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

The LCM of 391,304,190,494 is 7726160.

Find LCM of 391,304,190,494 with Prime Factorization

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

2 x 19 x 391 x 8 x 5 x 13 = 7726160

Therefore, the lowest common multiple of 391,304,190,494 is 7726160.

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.

391 x 304 x 190 x 494 = 11156575040

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.

391 : 1, 17, 23, 391

304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304

190 : 1, 2, 5, 10, 19, 38, 95, 190

494 : 1, 2, 13, 19, 26, 38, 247, 494

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,304,190,494, is 1.

Now, the common factors can be found like this.

391:17x 23

304:2x 2x 2x 2x 19

190:2x 5x 19

494:2x 13x 19

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 19x 19 = 1444

Therefore, the value for common factors is 1444.

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 = 11156575040/(1x1444)

LCM = 11156575040/1444

LCM = 7726160

Thus, we can understand that the LCM of 391,304,190,494 is 7726160.
