Given numbers are 405,669,571,361,343

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

The LCM of 405,669,571,361,343 is 6385535393895.

Find LCM of 405,669,571,361,343 with Prime Factorization

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

3 x 135 x 223 x 571 x 361 x 343 = 6385535393895

Therefore, the lowest common multiple of 405,669,571,361,343 is 6385535393895.

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 669 x 571 x 361 x 343 = 19156606181685

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

669 : 1, 3, 223, 669

571 : 1, 571

361 : 1, 19, 361

343 : 1, 7, 49, 343

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,669,571,361,343, is 1.

Now, the common factors can be found like this.

405:3x 3x 3x 3x 5

669:3x 223

571:571

361:19x 19

343:7x 7x 7

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

3 = 3

Therefore, the value for common factors is 3.

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 = 19156606181685/(1x3)

LCM = 19156606181685/3

LCM = 6385535393895

Thus, we can understand that the LCM of 405,669,571,361,343 is 6385535393895.
