Given numbers are 891,129,560,439

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

The LCM of 891,129,560,439 is 9418867920.

Find LCM of 891,129,560,439 with Prime Factorization

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

3 x 297 x 43 x 560 x 439 = 9418867920

Therefore, the lowest common multiple of 891,129,560,439 is 9418867920.

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.

891 x 129 x 560 x 439 = 28256603760

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.

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

129 : 1, 3, 43, 129

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

439 : 1, 439

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,129,560,439, is 1.

Now, the common factors can be found like this.

891:3x 3x 3x 3x 11

129:3x 43

560:2x 2x 2x 2x 5x 7

439:439

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

3 = 3

Therefore, the value for common factors is 3.

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 = 28256603760/(1x3)

LCM = 28256603760/3

LCM = 9418867920

Thus, we can understand that the LCM of 891,129,560,439 is 9418867920.
