Given numbers are 449,257,810,422

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

The LCM of 449,257,810,422 is 19721817630.

Find LCM of 449,257,810,422 with Prime Factorization

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

2 x 449 x 257 x 405 x 211 = 19721817630

Therefore, the lowest common multiple of 449,257,810,422 is 19721817630.

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.

449 x 257 x 810 x 422 = 39443635260

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.

449 : 1, 449

257 : 1, 257

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

422 : 1, 2, 211, 422

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 449,257,810,422, is 1.

Now, the common factors can be found like this.

449:449

257:257

810:2x 3x 3x 3x 3x 5

422:2x 211

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

2 = 2

Therefore, the value for common factors is 2.

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 = 39443635260/(1x2)

LCM = 39443635260/2

LCM = 19721817630

Thus, we can understand that the LCM of 449,257,810,422 is 19721817630.
