Given numbers are 686,802,454,431,828

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

The LCM of 686,802,454,431,828 is 11142225838548.

Find LCM of 686,802,454,431,828 with Prime Factorization

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

2 x 343 x 401 x 227 x 431 x 414 = 11142225838548

Therefore, the lowest common multiple of 686,802,454,431,828 is 11142225838548.

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.

686 x 802 x 454 x 431 x 828 = 89137806708384

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.

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

802 : 1, 2, 401, 802

454 : 1, 2, 227, 454

431 : 1, 431

828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,802,454,431,828, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

802:2x 401

454:2x 227

431:431

828:2x 2x 3x 3x 23

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 2 = 8

Therefore, the value for common factors is 8.

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 = 89137806708384/(1x8)

LCM = 89137806708384/8

LCM = 11142225838548

Thus, we can understand that the LCM of 686,802,454,431,828 is 11142225838548.
