Calculate the LCM of 443,891,815,443

Given numbers are 443,891,815,443

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

The LCM of 443,891,815,443 is 321691095.

Find LCM of 443,891,815,443 with Prime Factorization


443 443, 891, 815, 443
1, 891, 815, 1

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

443 x 1 x 891 x 815 x 1 = 321691095

Therefore, the lowest common multiple of 443,891,815,443 is 321691095.

LCM Formula to Find Lowest Common Multiple of 443,891,815,443

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.

443 x 891 x 815 x 443 = 142509155085

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.

443 : 1, 443

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

815 : 1, 5, 163, 815

443 : 1, 443

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 443,891,815,443, is 1.

Now, the common factors can be found like this.

443:443

891:3x 3x 3x 3x 11

815:5x 163

443:443

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

443 = 443

Therefore, the value for common factors is 443.

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 = 142509155085/(1x443)

LCM = 142509155085/443

LCM = 321691095

Thus, we can understand that the LCM of 443,891,815,443 is 321691095.
