Given numbers are 838,419,221,439

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

The LCM of 838,419,221,439 is 81301922.

Find LCM of 838,419,221,439 with Prime Factorization

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

419 x 2 x 1 x 221 x 439 = 81301922

Therefore, the lowest common multiple of 838,419,221,439 is 81301922.

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.

838 x 419 x 221 x 439 = 34065505318

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.

838 : 1, 2, 419, 838

419 : 1, 419

221 : 1, 13, 17, 221

439 : 1, 439

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,419,221,439, is 1.

Now, the common factors can be found like this.

838:2x 419

419:419

221:13x 17

439:439

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

419 = 419

Therefore, the value for common factors is 419.

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 = 34065505318/(1x419)

LCM = 34065505318/419

LCM = 81301922

Thus, we can understand that the LCM of 838,419,221,439 is 81301922.
