Given numbers are 681,393,609,729,681

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

The LCM of 681,393,609,729,681 is 4400689419.

Find LCM of 681,393,609,729,681 with Prime Factorization

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

3 x 227 x 1 x 131 x 203 x 243 x 1 = 4400689419

Therefore, the lowest common multiple of 681,393,609,729,681 is 4400689419.

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 393 x 609 x 729 x 681 = 80915476347153

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

393 : 1, 3, 131, 393

609 : 1, 3, 7, 21, 29, 87, 203, 609

729 : 1, 3, 9, 27, 81, 243, 729

681 : 1, 3, 227, 681

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,393,609,729,681, is 3.

Now, the common factors can be found like this.

681:3x 227

393:3x 131

609:3x 7x 29

729:3x 3x 3x 3x 3x 3

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 3x 227 = 6129

Therefore, the value for common factors is 6129.

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 = 80915476347153/(3x6129)

LCM = 80915476347153/18387

LCM = 4400689419

Thus, we can understand that the LCM of 681,393,609,729,681 is 4400689419.
