Given numbers are 398,422,237,920

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

The LCM of 398,422,237,920 is 9155281560.

Find LCM of 398,422,237,920 with Prime Factorization

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

2 x 199 x 211 x 237 x 460 = 9155281560

Therefore, the lowest common multiple of 398,422,237,920 is 9155281560.

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 422 x 237 x 920 = 36621126240

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

422 : 1, 2, 211, 422

237 : 1, 3, 79, 237

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,422,237,920, is 1.

Now, the common factors can be found like this.

398:2x 199

422:2x 211

237:3x 79

920:2x 2x 2x 5x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 36621126240/(1x4)

LCM = 36621126240/4

LCM = 9155281560

Thus, we can understand that the LCM of 398,422,237,920 is 9155281560.
