Given numbers are 391,662,934,821

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

The LCM of 391,662,934,821 is 99241834694.

Find LCM of 391,662,934,821 with Prime Factorization

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

2 x 391 x 331 x 467 x 821 = 99241834694

Therefore, the lowest common multiple of 391,662,934,821 is 99241834694.

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 662 x 934 x 821 = 198483669388

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

662 : 1, 2, 331, 662

934 : 1, 2, 467, 934

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,662,934,821, is 1.

Now, the common factors can be found like this.

391:17x 23

662:2x 331

934:2x 467

821:821

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

2 = 2

Therefore, the value for common factors is 2.

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 = 198483669388/(1x2)

LCM = 198483669388/2

LCM = 99241834694

Thus, we can understand that the LCM of 391,662,934,821 is 99241834694.
