Given numbers are 817,916,743,129

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

The LCM of 817,916,743,129 is 1668121188.

Find LCM of 817,916,743,129 with Prime Factorization

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

43 x 19 x 916 x 743 x 3 = 1668121188

Therefore, the lowest common multiple of 817,916,743,129 is 1668121188.

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.

817 x 916 x 743 x 129 = 71729211084

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.

817 : 1, 19, 43, 817

916 : 1, 2, 4, 229, 458, 916

743 : 1, 743

129 : 1, 3, 43, 129

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,916,743,129, is 1.

Now, the common factors can be found like this.

817:19x 43

916:2x 2x 229

743:743

129:3x 43

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

43 = 43

Therefore, the value for common factors is 43.

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 = 71729211084/(1x43)

LCM = 71729211084/43

LCM = 1668121188

Thus, we can understand that the LCM of 817,916,743,129 is 1668121188.
