Given numbers are 813,813,810

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

The LCM of 813,813,810 is 219510.

Find LCM of 813,813,810 with Prime Factorization

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

3 x 271 x 1 x 1 x 270 = 219510

Therefore, the lowest common multiple of 813,813,810 is 219510.

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 813 x 810 = 535384890

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

813 : 1, 3, 271, 813

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,813,810, is 3.

Now, the common factors can be found like this.

813:3x 271

813:3x 271

810:2x 3x 3x 3x 3x 5

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

3x 271 = 813

Therefore, the value for common factors is 813.

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 = 535384890/(3x813)

LCM = 535384890/2439

LCM = 219510

Thus, we can understand that the LCM of 813,813,810 is 219510.
