Given numbers are 218,218,634,538

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

The LCM of 218,218,634,538 is 18589514.

Find LCM of 218,218,634,538 with Prime Factorization

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

2 x 109 x 1 x 1 x 317 x 269 = 18589514

Therefore, the lowest common multiple of 218,218,634,538 is 18589514.

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.

218 x 218 x 634 x 538 = 16210056208

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.

218 : 1, 2, 109, 218

218 : 1, 2, 109, 218

634 : 1, 2, 317, 634

538 : 1, 2, 269, 538

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,218,634,538, is 2.

Now, the common factors can be found like this.

218:2x 109

218:2x 109

634:2x 317

538:2x 269

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 109 = 436

Therefore, the value for common factors is 436.

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 = 16210056208/(2x436)

LCM = 16210056208/872

LCM = 18589514

Thus, we can understand that the LCM of 218,218,634,538 is 18589514.
