Given numbers are 399,581,427,881,518

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

The LCM of 399,581,427,881,518 is 131700811578.

Find LCM of 399,581,427,881,518 with Prime Factorization

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

7 x 57 x 83 x 61 x 881 x 74 = 131700811578

Therefore, the lowest common multiple of 399,581,427,881,518 is 131700811578.

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.

399 x 581 x 427 x 881 x 518 = 45173378371254

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.

399 : 1, 3, 7, 19, 21, 57, 133, 399

581 : 1, 7, 83, 581

427 : 1, 7, 61, 427

881 : 1, 881

518 : 1, 2, 7, 14, 37, 74, 259, 518

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,581,427,881,518, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

581:7x 83

427:7x 61

881:881

518:2x 7x 37

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

7x 7x 7 = 343

Therefore, the value for common factors is 343.

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 = 45173378371254/(1x343)

LCM = 45173378371254/343

LCM = 131700811578

Thus, we can understand that the LCM of 399,581,427,881,518 is 131700811578.
