Given numbers are 813,543,891,326,645

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

The LCM of 813,543,891,326,645 is 3063244269690.

Find LCM of 813,543,891,326,645 with Prime Factorization

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

3 x 271 x 181 x 297 x 326 x 215 = 3063244269690

Therefore, the lowest common multiple of 813,543,891,326,645 is 3063244269690.

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 543 x 891 x 326 x 645 = 82707595281630

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

543 : 1, 3, 181, 543

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

326 : 1, 2, 163, 326

645 : 1, 3, 5, 15, 43, 129, 215, 645

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,543,891,326,645, is 1.

Now, the common factors can be found like this.

813:3x 271

543:3x 181

891:3x 3x 3x 3x 11

326:2x 163

645:3x 5x 43

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

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 82707595281630/(1x27)

LCM = 82707595281630/27

LCM = 3063244269690

Thus, we can understand that the LCM of 813,543,891,326,645 is 3063244269690.
