Given numbers are 321,645,841,447

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

The LCM of 321,645,841,447 is 8648200635.

Find LCM of 321,645,841,447 with Prime Factorization

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

3 x 107 x 215 x 841 x 149 = 8648200635

Therefore, the lowest common multiple of 321,645,841,447 is 8648200635.

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.

321 x 645 x 841 x 447 = 77833805715

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.

321 : 1, 3, 107, 321

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

841 : 1, 29, 841

447 : 1, 3, 149, 447

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,645,841,447, is 1.

Now, the common factors can be found like this.

321:3x 107

645:3x 5x 43

841:29x 29

447:3x 149

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 77833805715/(1x9)

LCM = 77833805715/9

LCM = 8648200635

Thus, we can understand that the LCM of 321,645,841,447 is 8648200635.
