Given numbers are 398,331,398,662

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

The LCM of 398,331,398,662 is 131738.

Find LCM of 398,331,398,662 with Prime Factorization

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

2 x 199 x 331 x 1 x 1 x 1 x 1 = 131738

Therefore, the lowest common multiple of 398,331,398,662 is 131738.

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.

398 x 331 x 398 x 662 = 34709801288

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.

398 : 1, 2, 199, 398

331 : 1, 331

398 : 1, 2, 199, 398

662 : 1, 2, 331, 662

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,331,398,662, is 1.

Now, the common factors can be found like this.

398:2x 199

331:331

398:2x 199

662:2x 331

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 199x 331 = 263476

Therefore, the value for common factors is 263476.

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 = 34709801288/(1x263476)

LCM = 34709801288/263476

LCM = 131738

Thus, we can understand that the LCM of 398,331,398,662 is 131738.
