I believe the number you are looking for is 96.
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.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

This follows from the property that the set of integers is closed under addition. This means that any two integers, when added together, must always result in a whole number.
44. Also works for 36, 63.
Because it may have a deciml in it
