Given numbers are 897,801,455,660,809

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

The LCM of 897,801,455,660,809 is 298382224140.

Find LCM of 897,801,455,660,809 with Prime Factorization

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

3 x 5 x 13 x 23 x 267 x 7 x 44 x 809 = 298382224140

Therefore, the lowest common multiple of 897,801,455,660,809 is 298382224140.

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.

897 x 801 x 455 x 660 x 809 = 174553601121900

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.

897 : 1, 3, 13, 23, 39, 69, 299, 897

801 : 1, 3, 9, 89, 267, 801

455 : 1, 5, 7, 13, 35, 65, 91, 455

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

809 : 1, 809

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,801,455,660,809, is 1.

Now, the common factors can be found like this.

897:3x 13x 23

801:3x 3x 89

455:5x 7x 13

660:2x 2x 3x 5x 11

809:809

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 5x 13 = 585

Therefore, the value for common factors is 585.

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 = 174553601121900/(1x585)

LCM = 174553601121900/585

LCM = 298382224140

Thus, we can understand that the LCM of 897,801,455,660,809 is 298382224140.
