Given numbers are 686,913,792,456

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

The LCM of 686,913,792,456 is 428401512.

Find LCM of 686,913,792,456 with Prime Factorization

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

2 x 2 x 2 x 3 x 11 x 343 x 83 x 3 x 19 = 428401512

Therefore, the lowest common multiple of 686,913,792,456 is 428401512.

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 913 x 792 x 456 = 226195998336

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

913 : 1, 11, 83, 913

792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,913,792,456, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

913:11x 83

792:2x 2x 2x 3x 3x 11

456:2x 2x 2x 3x 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 2x 2x 3x 11 = 528

Therefore, the value for common factors is 528.

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 = 226195998336/(1x528)

LCM = 226195998336/528

LCM = 428401512

Thus, we can understand that the LCM of 686,913,792,456 is 428401512.
