Given numbers are 394,197,617,447

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

The LCM of 394,197,617,447 is 108664806.

Find LCM of 394,197,617,447 with Prime Factorization

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

197 x 2 x 1 x 617 x 447 = 108664806

Therefore, the lowest common multiple of 394,197,617,447 is 108664806.

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.

394 x 197 x 617 x 447 = 21406966782

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.

394 : 1, 2, 197, 394

197 : 1, 197

617 : 1, 617

447 : 1, 3, 149, 447

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,197,617,447, is 1.

Now, the common factors can be found like this.

394:2x 197

197:197

617:617

447:3x 149

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

197 = 197

Therefore, the value for common factors is 197.

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 = 21406966782/(1x197)

LCM = 21406966782/197

LCM = 108664806

Thus, we can understand that the LCM of 394,197,617,447 is 108664806.
