Given numbers are 392,394,323,391

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

The LCM of 392,394,323,391 is 573697096.

Find LCM of 392,394,323,391 with Prime Factorization

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

2 x 17 x 196 x 197 x 19 x 23 = 573697096

Therefore, the lowest common multiple of 392,394,323,391 is 573697096.

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.

392 x 394 x 323 x 391 = 19505701264

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.

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

394 : 1, 2, 197, 394

323 : 1, 17, 19, 323

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,394,323,391, is 1.

Now, the common factors can be found like this.

392:2x 2x 2x 7x 7

394:2x 197

323:17x 19

391:17x 23

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 19505701264/(1x34)

LCM = 19505701264/34

LCM = 573697096

Thus, we can understand that the LCM of 392,394,323,391 is 573697096.

Here are some samples of LCM of two or more Numbers calculations.
