Given numbers are 809,982,691,638,497

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

The LCM of 809,982,691,638,497 is 87033235429294.

Find LCM of 809,982,691,638,497 with Prime Factorization

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

2 x 809 x 491 x 691 x 319 x 497 = 87033235429294

Therefore, the lowest common multiple of 809,982,691,638,497 is 87033235429294.

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.

809 x 982 x 691 x 638 x 497 = 174066470858588

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.

809 : 1, 809

982 : 1, 2, 491, 982

691 : 1, 691

638 : 1, 2, 11, 22, 29, 58, 319, 638

497 : 1, 7, 71, 497

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 809,982,691,638,497, is 1.

Now, the common factors can be found like this.

809:809

982:2x 491

691:691

638:2x 11x 29

497:7x 71

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

2 = 2

Therefore, the value for common factors is 2.

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 = 174066470858588/(1x2)

LCM = 174066470858588/2

LCM = 87033235429294

Thus, we can understand that the LCM of 809,982,691,638,497 is 87033235429294.
