Given numbers are 981,291,317,218

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

The LCM of 981,291,317,218 is 60329538.

Find LCM of 981,291,317,218 with Prime Factorization

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

3 x 109 x 3 x 97 x 317 x 2 = 60329538

Therefore, the lowest common multiple of 981,291,317,218 is 60329538.

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.

981 x 291 x 317 x 218 = 19727758926

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.

981 : 1, 3, 9, 109, 327, 981

291 : 1, 3, 97, 291

317 : 1, 317

218 : 1, 2, 109, 218

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,291,317,218, is 1.

Now, the common factors can be found like this.

981:3x 3x 109

291:3x 97

317:317

218:2x 109

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

3x 109 = 327

Therefore, the value for common factors is 327.

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 = 19727758926/(1x327)

LCM = 19727758926/327

LCM = 60329538

Thus, we can understand that the LCM of 981,291,317,218 is 60329538.
