Given numbers are 381,669,327,654

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

The LCM of 381,669,327,654 is 18521934.

Find LCM of 381,669,327,654 with Prime Factorization

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

3 x 109 x 127 x 223 x 1 x 2 = 18521934

Therefore, the lowest common multiple of 381,669,327,654 is 18521934.

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 669 x 327 x 654 = 54510051762

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

669 : 1, 3, 223, 669

327 : 1, 3, 109, 327

654 : 1, 2, 3, 6, 109, 218, 327, 654

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,669,327,654, is 3.

Now, the common factors can be found like this.

381:3x 127

669:3x 223

327:3x 109

654:2x 3x 109

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

3x 3x 109 = 981

Therefore, the value for common factors is 981.

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 = 54510051762/(3x981)

LCM = 54510051762/2943

LCM = 18521934

Thus, we can understand that the LCM of 381,669,327,654 is 18521934.
