Given numbers are 998,408,639,505

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

The LCM of 998,408,639,505 is 21899373480.

Find LCM of 998,408,639,505 with Prime Factorization

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

2 x 3 x 499 x 68 x 213 x 505 = 21899373480

Therefore, the lowest common multiple of 998,408,639,505 is 21899373480.

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.

998 x 408 x 639 x 505 = 131396240880

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.

998 : 1, 2, 499, 998

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

639 : 1, 3, 9, 71, 213, 639

505 : 1, 5, 101, 505

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,408,639,505, is 1.

Now, the common factors can be found like this.

998:2x 499

408:2x 2x 2x 3x 17

639:3x 3x 71

505:5x 101

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 131396240880/(1x6)

LCM = 131396240880/6

LCM = 21899373480

Thus, we can understand that the LCM of 998,408,639,505 is 21899373480.

Here are some samples of LCM of two or more Numbers calculations.
