Given numbers are 891,421,879,344,399

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

The LCM of 891,421,879,344,399 is 5028488992296.

Find LCM of 891,421,879,344,399 with Prime Factorization

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

3 x 297 x 421 x 293 x 344 x 133 = 5028488992296

Therefore, the lowest common multiple of 891,421,879,344,399 is 5028488992296.

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 421 x 879 x 344 x 399 = 45256400930664

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

421 : 1, 421

879 : 1, 3, 293, 879

344 : 1, 2, 4, 8, 43, 86, 172, 344

399 : 1, 3, 7, 19, 21, 57, 133, 399

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,421,879,344,399, is 1.

Now, the common factors can be found like this.

891:3x 3x 3x 3x 11

421:421

879:3x 293

344:2x 2x 2x 43

399:3x 7x 19

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 = 45256400930664/(1x9)

LCM = 45256400930664/9

LCM = 5028488992296

Thus, we can understand that the LCM of 891,421,879,344,399 is 5028488992296.
