Given numbers are 422,528,449,990

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

The LCM of 422,528,449,990 is 750332880.

Find LCM of 422,528,449,990 with Prime Factorization

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

2 x 3 x 11 x 211 x 8 x 449 x 15 = 750332880

Therefore, the lowest common multiple of 422,528,449,990 is 750332880.

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 528 x 449 x 990 = 99043940160

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

528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528

449 : 1, 449

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,528,449,990, is 1.

Now, the common factors can be found like this.

422:2x 211

528:2x 2x 2x 2x 3x 11

449:449

990:2x 3x 3x 5x 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 2x 3x 11 = 132

Therefore, the value for common factors is 132.

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 = 99043940160/(1x132)

LCM = 99043940160/132

LCM = 750332880

Thus, we can understand that the LCM of 422,528,449,990 is 750332880.
