Given numbers are 813,791,807

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

The LCM of 813,791,807 is 172989327.

Find LCM of 813,791,807 with Prime Factorization

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

3 x 271 x 791 x 269 = 172989327

Therefore, the lowest common multiple of 813,791,807 is 172989327.

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 791 x 807 = 518967981

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

791 : 1, 7, 113, 791

807 : 1, 3, 269, 807

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,791,807, is 1.

Now, the common factors can be found like this.

813:3x 271

791:7x 113

807:3x 269

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

3 = 3

Therefore, the value for common factors is 3.

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 = 518967981/(1x3)

LCM = 518967981/3

LCM = 172989327

Thus, we can understand that the LCM of 813,791,807 is 172989327.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 745, 527, 549
