Given numbers are 388,781,213,187

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

The LCM of 388,781,213,187 is 15454428.

Find LCM of 388,781,213,187 with Prime Factorization

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

11 x 71 x 388 x 1 x 3 x 17 = 15454428

Therefore, the lowest common multiple of 388,781,213,187 is 15454428.

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.

388 x 781 x 213 x 187 = 12069908268

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.

388 : 1, 2, 4, 97, 194, 388

781 : 1, 11, 71, 781

213 : 1, 3, 71, 213

187 : 1, 11, 17, 187

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,781,213,187, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

781:11x 71

213:3x 71

187:11x 17

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

11x 71 = 781

Therefore, the value for common factors is 781.

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 = 12069908268/(1x781)

LCM = 12069908268/781

LCM = 15454428

Thus, we can understand that the LCM of 388,781,213,187 is 15454428.
