Given numbers are 405,489,163,457

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

The LCM of 405,489,163,457 is 30168855.

Find LCM of 405,489,163,457 with Prime Factorization

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

3 x 163 x 135 x 1 x 1 x 457 = 30168855

Therefore, the lowest common multiple of 405,489,163,457 is 30168855.

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.

405 x 489 x 163 x 457 = 14752570095

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.

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

489 : 1, 3, 163, 489

163 : 1, 163

457 : 1, 457

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,489,163,457, is 1.

Now, the common factors can be found like this.

405:3x 3x 3x 3x 5

489:3x 163

163:163

457:457

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

3x 163 = 489

Therefore, the value for common factors is 489.

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 = 14752570095/(1x489)

LCM = 14752570095/489

LCM = 30168855

Thus, we can understand that the LCM of 405,489,163,457 is 30168855.
