Given numbers are 406,831,745,447

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

The LCM of 406,831,745,447 is 251352570.

Find LCM of 406,831,745,447 with Prime Factorization

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

3 x 149 x 406 x 277 x 5 x 1 = 251352570

Therefore, the lowest common multiple of 406,831,745,447 is 251352570.

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.

406 x 831 x 745 x 447 = 112354598790

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.

406 : 1, 2, 7, 14, 29, 58, 203, 406

831 : 1, 3, 277, 831

745 : 1, 5, 149, 745

447 : 1, 3, 149, 447

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,831,745,447, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

831:3x 277

745:5x 149

447:3x 149

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

3x 149 = 447

Therefore, the value for common factors is 447.

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 = 112354598790/(1x447)

LCM = 112354598790/447

LCM = 251352570

Thus, we can understand that the LCM of 406,831,745,447 is 251352570.
