Given numbers are 915,405,903,390,194

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

The LCM of 915,405,903,390,194 is 18754109010.

Find LCM of 915,405,903,390,194 with Prime Factorization

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

2 x 3 x 5 x 61 x 27 x 301 x 13 x 97 = 18754109010

Therefore, the lowest common multiple of 915,405,903,390,194 is 18754109010.

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.

915 x 405 x 903 x 390 x 194 = 25318047163500

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.

915 : 1, 3, 5, 15, 61, 183, 305, 915

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

903 : 1, 3, 7, 21, 43, 129, 301, 903

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

194 : 1, 2, 97, 194

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 915,405,903,390,194, is 1.

Now, the common factors can be found like this.

915:3x 5x 61

405:3x 3x 3x 3x 5

903:3x 7x 43

390:2x 3x 5x 13

194:2x 97

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

2x 3x 3x 3x 5x 5 = 1350

Therefore, the value for common factors is 1350.

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 = 25318047163500/(1x1350)

LCM = 25318047163500/1350

LCM = 18754109010

Thus, we can understand that the LCM of 915,405,903,390,194 is 18754109010.
