Given numbers are 445,548,555,489,721

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

The LCM of 445,548,555,489,721 is 3181166624580.

Find LCM of 445,548,555,489,721 with Prime Factorization

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

3 x 5 x 89 x 548 x 37 x 163 x 721 = 3181166624580

Therefore, the lowest common multiple of 445,548,555,489,721 is 3181166624580.

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.

445 x 548 x 555 x 489 x 721 = 47717499368700

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.

445 : 1, 5, 89, 445

548 : 1, 2, 4, 137, 274, 548

555 : 1, 3, 5, 15, 37, 111, 185, 555

489 : 1, 3, 163, 489

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,548,555,489,721, is 1.

Now, the common factors can be found like this.

445:5x 89

548:2x 2x 137

555:3x 5x 37

489:3x 163

721:7x 103

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 47717499368700/(1x15)

LCM = 47717499368700/15

LCM = 3181166624580

Thus, we can understand that the LCM of 445,548,555,489,721 is 3181166624580.
