Given numbers are 687,879,491,491

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

The LCM of 687,879,491,491 is 98833881.

Find LCM of 687,879,491,491 with Prime Factorization

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

3 x 491 x 229 x 293 x 1 x 1 = 98833881

Therefore, the lowest common multiple of 687,879,491,491 is 98833881.

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 879 x 491 x 491 = 145582306713

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

879 : 1, 3, 293, 879

491 : 1, 491

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,879,491,491, is 1.

Now, the common factors can be found like this.

687:3x 229

879:3x 293

491:491

491:491

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

3x 491 = 1473

Therefore, the value for common factors is 1473.

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 = 145582306713/(1x1473)

LCM = 145582306713/1473

LCM = 98833881

Thus, we can understand that the LCM of 687,879,491,491 is 98833881.
