Given numbers are 478,609,857,857

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

The LCM of 478,609,857,857 is 249474414.

Find LCM of 478,609,857,857 with Prime Factorization

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

857 x 478 x 609 x 1 x 1 = 249474414

Therefore, the lowest common multiple of 478,609,857,857 is 249474414.

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.

478 x 609 x 857 x 857 = 213799572798

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.

478 : 1, 2, 239, 478

609 : 1, 3, 7, 21, 29, 87, 203, 609

857 : 1, 857

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,609,857,857, is 1.

Now, the common factors can be found like this.

478:2x 239

609:3x 7x 29

857:857

857:857

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

857 = 857

Therefore, the value for common factors is 857.

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 = 213799572798/(1x857)

LCM = 213799572798/857

LCM = 249474414

Thus, we can understand that the LCM of 478,609,857,857 is 249474414.
