Given numbers are 381,654,669,351

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

The LCM of 381,654,669,351 is 2167066278.

Find LCM of 381,654,669,351 with Prime Factorization

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

3 x 127 x 218 x 223 x 117 = 2167066278

Therefore, the lowest common multiple of 381,654,669,351 is 2167066278.

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 654 x 669 x 351 = 58510789506

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

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

669 : 1, 3, 223, 669

351 : 1, 3, 9, 13, 27, 39, 117, 351

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,654,669,351, is 3.

Now, the common factors can be found like this.

381:3x 127

654:2x 3x 109

669:3x 223

351:3x 3x 3x 13

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 58510789506/(3x9)

LCM = 58510789506/27

LCM = 2167066278

Thus, we can understand that the LCM of 381,654,669,351 is 2167066278.
