Given numbers are 681,707,609,863

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

The LCM of 681,707,609,863 is 12049674609.

Find LCM of 681,707,609,863 with Prime Factorization

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

3 x 7 x 227 x 101 x 29 x 863 = 12049674609

Therefore, the lowest common multiple of 681,707,609,863 is 12049674609.

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 707 x 609 x 863 = 253043166789

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

707 : 1, 7, 101, 707

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

863 : 1, 863

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,707,609,863, is 1.

Now, the common factors can be found like this.

681:3x 227

707:7x 101

609:3x 7x 29

863:863

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 253043166789/(1x21)

LCM = 253043166789/21

LCM = 12049674609

Thus, we can understand that the LCM of 681,707,609,863 is 12049674609.
