Given numbers are 247,171,803,417

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

The LCM of 247,171,803,417 is 248124591.

Find LCM of 247,171,803,417 with Prime Factorization

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

3 x 19 x 13 x 3 x 803 x 139 = 248124591

Therefore, the lowest common multiple of 247,171,803,417 is 248124591.

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.

247 x 171 x 803 x 417 = 14143101687

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.

247 : 1, 13, 19, 247

171 : 1, 3, 9, 19, 57, 171

803 : 1, 11, 73, 803

417 : 1, 3, 139, 417

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,171,803,417, is 1.

Now, the common factors can be found like this.

247:13x 19

171:3x 3x 19

803:11x 73

417:3x 139

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

3x 19 = 57

Therefore, the value for common factors is 57.

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 = 14143101687/(1x57)

LCM = 14143101687/57

LCM = 248124591

Thus, we can understand that the LCM of 247,171,803,417 is 248124591.
