Given numbers are 331,340,662,380

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

The LCM of 331,340,662,380 is 2138260.

Find LCM of 331,340,662,380 with Prime Factorization

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

2 x 2 x 5 x 331 x 1 x 17 x 1 x 19 = 2138260

Therefore, the lowest common multiple of 331,340,662,380 is 2138260.

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.

331 x 340 x 662 x 380 = 28310562400

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.

331 : 1, 331

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

662 : 1, 2, 331, 662

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,340,662,380, is 1.

Now, the common factors can be found like this.

331:331

340:2x 2x 5x 17

662:2x 331

380:2x 2x 5x 19

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 5x 331 = 13240

Therefore, the value for common factors is 13240.

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 = 28310562400/(1x13240)

LCM = 28310562400/13240

LCM = 2138260

Thus, we can understand that the LCM of 331,340,662,380 is 2138260.
