Given numbers are 399,647,998,998

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

The LCM of 399,647,998,998 is 257636694.

Find LCM of 399,647,998,998 with Prime Factorization

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

2 x 499 x 399 x 647 x 1 x 1 = 257636694

Therefore, the lowest common multiple of 399,647,998,998 is 257636694.

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 647 x 998 x 998 = 257121420612

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

647 : 1, 647

998 : 1, 2, 499, 998

998 : 1, 2, 499, 998

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,647,998,998, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

647:647

998:2x 499

998:2x 499

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

2x 499 = 998

Therefore, the value for common factors is 998.

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 = 257121420612/(1x998)

LCM = 257121420612/998

LCM = 257636694

Thus, we can understand that the LCM of 399,647,998,998 is 257636694.
