Given numbers are 998,395,642,717

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

The LCM of 998,395,642,717 is 30243396990.

Find LCM of 998,395,642,717 with Prime Factorization

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

2 x 3 x 499 x 395 x 107 x 239 = 30243396990

Therefore, the lowest common multiple of 998,395,642,717 is 30243396990.

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 395 x 642 x 717 = 181460381940

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

395 : 1, 5, 79, 395

642 : 1, 2, 3, 6, 107, 214, 321, 642

717 : 1, 3, 239, 717

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,395,642,717, is 1.

Now, the common factors can be found like this.

998:2x 499

395:5x 79

642:2x 3x 107

717:3x 239

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 = 181460381940/(1x6)

LCM = 181460381940/6

LCM = 30243396990

Thus, we can understand that the LCM of 998,395,642,717 is 30243396990.
