Given numbers are 813,828,521,916

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

The LCM of 813,828,521,916 is 26771507892.

Find LCM of 813,828,521,916 with Prime Factorization

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

2 x 2 x 3 x 271 x 69 x 521 x 229 = 26771507892

Therefore, the lowest common multiple of 813,828,521,916 is 26771507892.

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.

813 x 828 x 521 x 916 = 321258094704

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.

813 : 1, 3, 271, 813

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

521 : 1, 521

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,828,521,916, is 1.

Now, the common factors can be found like this.

813:3x 271

828:2x 2x 3x 3x 23

521:521

916:2x 2x 229

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 3 = 12

Therefore, the value for common factors is 12.

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 = 321258094704/(1x12)

LCM = 321258094704/12

LCM = 26771507892

Thus, we can understand that the LCM of 813,828,521,916 is 26771507892.
