Given numbers are 687,511,916,843

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

The LCM of 687,511,916,843 is 394588068.

Find LCM of 687,511,916,843 with Prime Factorization

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

3 x 229 x 1 x 511 x 4 x 281 = 394588068

Therefore, the lowest common multiple of 687,511,916,843 is 394588068.

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.

687 x 511 x 916 x 843 = 271082002716

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.

687 : 1, 3, 229, 687

511 : 1, 7, 73, 511

916 : 1, 2, 4, 229, 458, 916

843 : 1, 3, 281, 843

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,511,916,843, is 1.

Now, the common factors can be found like this.

687:3x 229

511:7x 73

916:2x 2x 229

843:3x 281

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

3x 229 = 687

Therefore, the value for common factors is 687.

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 = 271082002716/(1x687)

LCM = 271082002716/687

LCM = 394588068

Thus, we can understand that the LCM of 687,511,916,843 is 394588068.
