Given numbers are 398,988,554,440

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

The LCM of 398,988,554,440 is 5990767640.

Find LCM of 398,988,554,440 with Prime Factorization

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

2 x 2 x 199 x 247 x 277 x 110 = 5990767640

Therefore, the lowest common multiple of 398,988,554,440 is 5990767640.

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.

398 x 988 x 554 x 440 = 95852282240

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.

398 : 1, 2, 199, 398

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

554 : 1, 2, 277, 554

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,988,554,440, is 2.

Now, the common factors can be found like this.

398:2x 199

988:2x 2x 13x 19

554:2x 277

440:2x 2x 2x 5x 11

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

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 95852282240/(2x8)

LCM = 95852282240/16

LCM = 5990767640

Thus, we can understand that the LCM of 398,988,554,440 is 5990767640.
