Given numbers are 331,381,161,389,230

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

The LCM of 331,381,161,389,230 is 78982058190.

Find LCM of 331,381,161,389,230 with Prime Factorization

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

23 x 331 x 381 x 7 x 389 x 10 = 78982058190

Therefore, the lowest common multiple of 331,381,161,389,230 is 78982058190.

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 381 x 161 x 389 x 230 = 1816587338370

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

381 : 1, 3, 127, 381

161 : 1, 7, 23, 161

389 : 1, 389

230 : 1, 2, 5, 10, 23, 46, 115, 230

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,381,161,389,230, is 1.

Now, the common factors can be found like this.

331:331

381:3x 127

161:7x 23

389:389

230:2x 5x 23

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

23 = 23

Therefore, the value for common factors is 23.

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 = 1816587338370/(1x23)

LCM = 1816587338370/23

LCM = 78982058190

Thus, we can understand that the LCM of 331,381,161,389,230 is 78982058190.
