Given numbers are 398,891,478,187

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

The LCM of 398,891,478,187 is 1440812934.

Find LCM of 398,891,478,187 with Prime Factorization

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

2 x 11 x 199 x 81 x 239 x 17 = 1440812934

Therefore, the lowest common multiple of 398,891,478,187 is 1440812934.

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 891 x 478 x 187 = 31697884548

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

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

478 : 1, 2, 239, 478

187 : 1, 11, 17, 187

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,891,478,187, is 1.

Now, the common factors can be found like this.

398:2x 199

891:3x 3x 3x 3x 11

478:2x 239

187:11x 17

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 31697884548/(1x22)

LCM = 31697884548/22

LCM = 1440812934

Thus, we can understand that the LCM of 398,891,478,187 is 1440812934.
