Given numbers are 422,872,291,891

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

The LCM of 422,872,291,891 is 15901876584.

Find LCM of 422,872,291,891 with Prime Factorization

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

2 x 3 x 211 x 436 x 97 x 297 = 15901876584

Therefore, the lowest common multiple of 422,872,291,891 is 15901876584.

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.

422 x 872 x 291 x 891 = 95411259504

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.

422 : 1, 2, 211, 422

872 : 1, 2, 4, 8, 109, 218, 436, 872

291 : 1, 3, 97, 291

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,872,291,891, is 1.

Now, the common factors can be found like this.

422:2x 211

872:2x 2x 2x 109

291:3x 97

891:3x 3x 3x 3x 11

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 95411259504/(1x6)

LCM = 95411259504/6

LCM = 15901876584

Thus, we can understand that the LCM of 422,872,291,891 is 15901876584.
