Given numbers are 681,218,872,790

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

The LCM of 681,218,872,790 is 234563640.

Find LCM of 681,218,872,790 with Prime Factorization

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

2 x 109 x 681 x 1 x 4 x 395 = 234563640

Therefore, the lowest common multiple of 681,218,872,790 is 234563640.

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.

681 x 218 x 872 x 790 = 102269747040

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.

681 : 1, 3, 227, 681

218 : 1, 2, 109, 218

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

790 : 1, 2, 5, 10, 79, 158, 395, 790

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,218,872,790, is 1.

Now, the common factors can be found like this.

681:3x 227

218:2x 109

872:2x 2x 2x 109

790:2x 5x 79

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 = 102269747040/(1x436)

LCM = 102269747040/436

LCM = 234563640

Thus, we can understand that the LCM of 681,218,872,790 is 234563640.
