Given numbers are 399,387,687,681,869

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

The LCM of 399,387,687,681,869 is 2325111166917.

Find LCM of 399,387,687,681,869 with Prime Factorization

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

3 x 133 x 129 x 229 x 227 x 869 = 2325111166917

Therefore, the lowest common multiple of 399,387,687,681,869 is 2325111166917.

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 387 x 687 x 681 x 869 = 62778001506759

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

387 : 1, 3, 9, 43, 129, 387

687 : 1, 3, 229, 687

681 : 1, 3, 227, 681

869 : 1, 11, 79, 869

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,387,687,681,869, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

387:3x 3x 43

687:3x 229

681:3x 227

869:11x 79

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 3 = 27

Therefore, the value for common factors is 27.

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 = 62778001506759/(1x27)

LCM = 62778001506759/27

LCM = 2325111166917

Thus, we can understand that the LCM of 399,387,687,681,869 is 2325111166917.
