Given numbers are 381,181,616,905

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

The LCM of 381,181,616,905 is 212399880.

Find LCM of 381,181,616,905 with Prime Factorization

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

181 x 381 x 1 x 616 x 5 = 212399880

Therefore, the lowest common multiple of 381,181,616,905 is 212399880.

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.

381 x 181 x 616 x 905 = 38444378280

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.

381 : 1, 3, 127, 381

181 : 1, 181

616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616

905 : 1, 5, 181, 905

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,181,616,905, is 1.

Now, the common factors can be found like this.

381:3x 127

181:181

616:2x 2x 2x 7x 11

905:5x 181

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

181 = 181

Therefore, the value for common factors is 181.

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 = 38444378280/(1x181)

LCM = 38444378280/181

LCM = 212399880

Thus, we can understand that the LCM of 381,181,616,905 is 212399880.
