Given numbers are 998,443,102,391

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

The LCM of 998,443,102,391 is 518599722.

Find LCM of 998,443,102,391 with Prime Factorization

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

2 x 17 x 499 x 443 x 3 x 23 = 518599722

Therefore, the lowest common multiple of 998,443,102,391 is 518599722.

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 443 x 102 x 391 = 17632390548

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

443 : 1, 443

102 : 1, 2, 3, 6, 17, 34, 51, 102

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,443,102,391, is 1.

Now, the common factors can be found like this.

998:2x 499

443:443

102:2x 3x 17

391:17x 23

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 17632390548/(1x34)

LCM = 17632390548/34

LCM = 518599722

Thus, we can understand that the LCM of 998,443,102,391 is 518599722.
