Given numbers are 391,391,475,686

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

The LCM of 391,391,475,686 is 127407350.

Find LCM of 391,391,475,686 with Prime Factorization

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

17 x 23 x 1 x 1 x 475 x 686 = 127407350

Therefore, the lowest common multiple of 391,391,475,686 is 127407350.

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 391 x 475 x 686 = 49816273850

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

391 : 1, 17, 23, 391

475 : 1, 5, 19, 25, 95, 475

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,391,475,686, is 1.

Now, the common factors can be found like this.

391:17x 23

391:17x 23

475:5x 5x 19

686:2x 7x 7x 7

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

17x 23 = 391

Therefore, the value for common factors is 391.

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 = 49816273850/(1x391)

LCM = 49816273850/391

LCM = 127407350

Thus, we can understand that the LCM of 391,391,475,686 is 127407350.
