Given numbers are 638,878,259,442

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

The LCM of 638,878,259,442 is 16031613598.

Find LCM of 638,878,259,442 with Prime Factorization

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

2 x 319 x 439 x 259 x 221 = 16031613598

Therefore, the lowest common multiple of 638,878,259,442 is 16031613598.

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.

638 x 878 x 259 x 442 = 64126454392

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

878 : 1, 2, 439, 878

259 : 1, 7, 37, 259

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,878,259,442, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

878:2x 439

259:7x 37

442:2x 13x 17

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 64126454392/(1x4)

LCM = 64126454392/4

LCM = 16031613598

Thus, we can understand that the LCM of 638,878,259,442 is 16031613598.
