No. To find if a number is a factor of 3, add the number's digits. If the resulting number is a multiple of 3, then the original number is a multiple of 3. In 4339, the digits of the number added together is 19, which is not a multiple of 3.
There is a complement that when added equals one but you may be thinking of multiplying. A number times its reciprocal (multiplicative inverse) is equal to one. A number added to its additive inverse (opposite) is equal to zero.

The answer is 39. 3+9=12, 3x9=27. 12+27=39.

In a measurement the digits that are an approximation are only those in proper scientific notation. The more digits that are added to the number the more the number becomes exact.
