Given numbers are 215,445,745,405

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

The LCM of 215,445,745,405 is 230940315.

Find LCM of 215,445,745,405 with Prime Factorization

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

5 x 43 x 89 x 149 x 81 = 230940315

Therefore, the lowest common multiple of 215,445,745,405 is 230940315.

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.

215 x 445 x 745 x 405 = 28867539375

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.

215 : 1, 5, 43, 215

445 : 1, 5, 89, 445

745 : 1, 5, 149, 745

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

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,445,745,405, is 5.

Now, the common factors can be found like this.

215:5x 43

445:5x 89

745:5x 149

405:3x 3x 3x 3x 5

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 28867539375/(5x25)

LCM = 28867539375/125

LCM = 230940315

Thus, we can understand that the LCM of 215,445,745,405 is 230940315.
