Given numbers are 617,981,993,218

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

The LCM of 617,981,993,218 is 400693374.

Find LCM of 617,981,993,218 with Prime Factorization

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

3 x 109 x 617 x 3 x 331 x 2 = 400693374

Therefore, the lowest common multiple of 617,981,993,218 is 400693374.

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.

617 x 981 x 993 x 218 = 131026733298

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.

617 : 1, 617

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

993 : 1, 3, 331, 993

218 : 1, 2, 109, 218

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,981,993,218, is 1.

Now, the common factors can be found like this.

617:617

981:3x 3x 109

993:3x 331

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 = 131026733298/(1x327)

LCM = 131026733298/327

LCM = 400693374

Thus, we can understand that the LCM of 617,981,993,218 is 400693374.
