Given numbers are 393,422,311,590

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

The LCM of 393,422,311,590 is 15215541270.

Find LCM of 393,422,311,590 with Prime Factorization

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

2 x 393 x 211 x 311 x 295 = 15215541270

Therefore, the lowest common multiple of 393,422,311,590 is 15215541270.

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.

393 x 422 x 311 x 590 = 30431082540

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.

393 : 1, 3, 131, 393

422 : 1, 2, 211, 422

311 : 1, 311

590 : 1, 2, 5, 10, 59, 118, 295, 590

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,422,311,590, is 1.

Now, the common factors can be found like this.

393:3x 131

422:2x 211

311:311

590:2x 5x 59

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

2 = 2

Therefore, the value for common factors is 2.

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 = 30431082540/(1x2)

LCM = 30431082540/2

LCM = 15215541270

Thus, we can understand that the LCM of 393,422,311,590 is 15215541270.
