Given numbers are 394,488,442,822,394

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

The LCM of 394,488,442,822,394 is 8732129016.

Find LCM of 394,488,442,822,394 with Prime Factorization

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

2 x 197 x 1 x 244 x 221 x 411 x 1 = 8732129016

Therefore, the lowest common multiple of 394,488,442,822,394 is 8732129016.

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 488 x 442 x 822 x 394 = 27523670658432

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

488 : 1, 2, 4, 8, 61, 122, 244, 488

442 : 1, 2, 13, 17, 26, 34, 221, 442

822 : 1, 2, 3, 6, 137, 274, 411, 822

394 : 1, 2, 197, 394

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,488,442,822,394, is 2.

Now, the common factors can be found like this.

394:2x 197

488:2x 2x 2x 61

442:2x 13x 17

822:2x 3x 137

394:2x 197

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

2x 2x 2x 197 = 1576

Therefore, the value for common factors is 1576.

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 = 27523670658432/(2x1576)

LCM = 27523670658432/3152

LCM = 8732129016

Thus, we can understand that the LCM of 394,488,442,822,394 is 8732129016.
