Given numbers are 391,353,982,491

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

The LCM of 391,353,982,491 is 135538586.

Find LCM of 391,353,982,491 with Prime Factorization

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

491 x 391 x 353 x 2 x 1 = 135538586

Therefore, the lowest common multiple of 391,353,982,491 is 135538586.

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 353 x 982 x 491 = 66549445726

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

353 : 1, 353

982 : 1, 2, 491, 982

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,353,982,491, is 1.

Now, the common factors can be found like this.

391:17x 23

353:353

982:2x 491

491:491

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

491 = 491

Therefore, the value for common factors is 491.

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 = 66549445726/(1x491)

LCM = 66549445726/491

LCM = 135538586

Thus, we can understand that the LCM of 391,353,982,491 is 135538586.
