Given numbers are 270,489,489,681

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

The LCM of 270,489,489,681 is 9990270.

Find LCM of 270,489,489,681 with Prime Factorization

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

3 x 163 x 90 x 1 x 1 x 227 = 9990270

Therefore, the lowest common multiple of 270,489,489,681 is 9990270.

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.

270 x 489 x 489 x 681 = 43967178270

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.

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

489 : 1, 3, 163, 489

489 : 1, 3, 163, 489

681 : 1, 3, 227, 681

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 270,489,489,681, is 3.

Now, the common factors can be found like this.

270:2x 3x 3x 3x 5

489:3x 163

489:3x 163

681:3x 227

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

3x 3x 163 = 1467

Therefore, the value for common factors is 1467.

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 = 43967178270/(3x1467)

LCM = 43967178270/4401

LCM = 9990270

Thus, we can understand that the LCM of 270,489,489,681 is 9990270.
