Given numbers are 129,791,741,981

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

The LCM of 129,791,741,981 is 8241587991.

Find LCM of 129,791,741,981 with Prime Factorization

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

3 x 43 x 791 x 247 x 327 = 8241587991

Therefore, the lowest common multiple of 129,791,741,981 is 8241587991.

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.

129 x 791 x 741 x 981 = 74174291919

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.

129 : 1, 3, 43, 129

791 : 1, 7, 113, 791

741 : 1, 3, 13, 19, 39, 57, 247, 741

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 129,791,741,981, is 1.

Now, the common factors can be found like this.

129:3x 43

791:7x 113

741:3x 13x 19

981:3x 3x 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 3 = 9

Therefore, the value for common factors is 9.

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 = 74174291919/(1x9)

LCM = 74174291919/9

LCM = 8241587991

Thus, we can understand that the LCM of 129,791,741,981 is 8241587991.
