Given numbers are 398,966,204,813

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

The LCM of 398,966,204,813 is 1771244076.

Find LCM of 398,966,204,813 with Prime Factorization

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

2 x 3 x 199 x 161 x 34 x 271 = 1771244076

Therefore, the lowest common multiple of 398,966,204,813 is 1771244076.

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 966 x 204 x 813 = 63764786736

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

966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966

204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204

813 : 1, 3, 271, 813

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,966,204,813, is 1.

Now, the common factors can be found like this.

398:2x 199

966:2x 3x 7x 23

204:2x 2x 3x 17

813:3x 271

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 63764786736/(1x36)

LCM = 63764786736/36

LCM = 1771244076

Thus, we can understand that the LCM of 398,966,204,813 is 1771244076.
