Given numbers are 457,258,817,389

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

The LCM of 457,258,817,389 is 871443246.

Find LCM of 457,258,817,389 with Prime Factorization

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

43 x 457 x 6 x 19 x 389 = 871443246

Therefore, the lowest common multiple of 457,258,817,389 is 871443246.

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.

457 x 258 x 817 x 389 = 37472059578

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.

457 : 1, 457

258 : 1, 2, 3, 6, 43, 86, 129, 258

817 : 1, 19, 43, 817

389 : 1, 389

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 457,258,817,389, is 1.

Now, the common factors can be found like this.

457:457

258:2x 3x 43

817:19x 43

389:389

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

43 = 43

Therefore, the value for common factors is 43.

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 = 37472059578/(1x43)

LCM = 37472059578/43

LCM = 871443246

Thus, we can understand that the LCM of 457,258,817,389 is 871443246.
