Given numbers are 447,457,921,509

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

The LCM of 447,457,921,509 is 31921249377.

Find LCM of 447,457,921,509 with Prime Factorization

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

3 x 149 x 457 x 307 x 509 = 31921249377

Therefore, the lowest common multiple of 447,457,921,509 is 31921249377.

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.

447 x 457 x 921 x 509 = 95763748131

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.

447 : 1, 3, 149, 447

457 : 1, 457

921 : 1, 3, 307, 921

509 : 1, 509

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 447,457,921,509, is 1.

Now, the common factors can be found like this.

447:3x 149

457:457

921:3x 307

509:509

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 = 95763748131/(1x3)

LCM = 95763748131/3

LCM = 31921249377

Thus, we can understand that the LCM of 447,457,921,509 is 31921249377.
