Given numbers are 18,581,814

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

The LCM of 18,581,814 is 4256406.

Find LCM of 18,581,814 with Prime Factorization

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

2 x 9 x 581 x 407 = 4256406

Therefore, the lowest common multiple of 18,581,814 is 4256406.

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.

18 x 581 x 814 = 8512812

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.

18 : 1, 2, 3, 6, 9, 18

581 : 1, 7, 83, 581

814 : 1, 2, 11, 22, 37, 74, 407, 814

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 18,581,814, is 1.

Now, the common factors can be found like this.

18:2x 3x 3

581:7x 83

814:2x 11x 37

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

2 = 2

Therefore, the value for common factors is 2.

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 = 8512812/(1x2)

LCM = 8512812/2

LCM = 4256406

Thus, we can understand that the LCM of 18,581,814 is 4256406.

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

• LCM of 47, 496, 860
• LCM of 70, 118, 449
