Given numbers are 218,538,243,872

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

The LCM of 218,538,243,872 is 57000024.

Find LCM of 218,538,243,872 with Prime Factorization

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

2 x 109 x 1 x 269 x 243 x 4 = 57000024

Therefore, the lowest common multiple of 218,538,243,872 is 57000024.

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 538 x 243 x 872 = 24852010464

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

538 : 1, 2, 269, 538

243 : 1, 3, 9, 27, 81, 243

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,538,243,872, is 1.

Now, the common factors can be found like this.

218:2x 109

538:2x 269

243:3x 3x 3x 3x 3

872:2x 2x 2x 109

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 = 24852010464/(1x436)

LCM = 24852010464/436

LCM = 57000024

Thus, we can understand that the LCM of 218,538,243,872 is 57000024.
