Given numbers are 419,257,408,257

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

The LCM of 419,257,408,257 is 43934664.

Find LCM of 419,257,408,257 with Prime Factorization

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

257 x 419 x 1 x 408 x 1 = 43934664

Therefore, the lowest common multiple of 419,257,408,257 is 43934664.

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.

419 x 257 x 408 x 257 = 11291208648

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.

419 : 1, 419

257 : 1, 257

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 419,257,408,257, is 1.

Now, the common factors can be found like this.

419:419

257:257

408:2x 2x 2x 3x 17

257:257

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

257 = 257

Therefore, the value for common factors is 257.

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 = 11291208648/(1x257)

LCM = 11291208648/257

LCM = 43934664

Thus, we can understand that the LCM of 419,257,408,257 is 43934664.
