Multiplicative Inverse of 641

Multiplicative Inverse of 641 is defined as what you can multiply with 641 to get 1.
If the Multiplicative Inverse of 641 is x, the problem can be written as a function as follows:
641(x) = 1
Thus, to get the answer, we divide 1 by 641 like this:
1 / 641 = 0.00156006
Note that the answer is rounded to the nearest 8 decimals if necessary. We can prove that the answer is correct: 0.00156006 multiplied by 641 equals 1.
The Multiplicative Inverse of postive 641 has a positive answer and the Multiplicative Inverse of negative 641 has a negative answer. Therefore, the Multiplicative Inverse of -641 is -0.00156006.
