The answer depends on what information you have. Given only one number, all that can be said is that the base is larger than the largest digit appearing in the number.
Equations will not help if there are no "carries". For example,
For example, 10 + 12 = 22 is true in any base greater than or equal to 3.
[In base 3, it is 3+5=8, in base 4, it is 4+6=10, in base 500 it is 500+502=1002, in base e (= 2.7183...) it is 2.7183+4.7183 =7.4366 (approx).]
If you mean a number system analogous (similar) to our decimal system, the base for such a number system can be any integer, 2 or greater. In other words, the base can be 2, 3, 4, 5, etc. You need as many different digits as the size of the base (decimal is in base 10, so you need 10 different digits).
In any system of counting, there are exactly the same number of digits as the base. They go from 0 to one less than the base.
The base-2 (binary) system is simpler than a system based on any higher integer. In a way, it is the simplest possible number system.
A digit in math is a component of a natural number which is less than the base of the number system you are using. Natural numbers are all of the non-negative integers, sometimes including zero. So in the decimal number system, which has a base of 10, a digit is any number from 0 to 9. If you are using the binary number system, which has a base of 2, a digit can only be a 0 or a 1. If you are using the hexadecimal number system, which has a base of 16, a digit is any number from 0 to 15 (the numbers 10-15 are generally represented as A, B, C, D, E, F). If you are using the Sexagesimal number system, which has a base of 60, a digit is any number from 0 to 59. This is the number system which the Babylonians used, which is one of the reasons why we divide an hour into 60 minutes, and a minute into 60 seconds. This is also why we have 360 degrees to a circle.
There is no smallest number, in any base.
A number system used to represent any number by a 1 or a zero is a binary system or a base 2 number system.
Any number system with a base of 6 or greater.

"Non-base" typically refers to any number system that is not base 10 (decimal), such as binary (base 2), hexadecimal (base 16), or octal (base 8). These non-base number systems are used in computer science and mathematics for various purposes.
A number is divisible by 10 when the one's digit is a 0. Note that this is true for ANY number system, regardless of the base.
This base 60 number system was used in 1800b.c
There is no smallest number, in any base.
No, it's false. "Base two" is another name for the "binary" number system ... the system running inside any kind of digital hardware, including computers. The corresponding name for the decimal number system is "base ten". The 'base' tells you how many digits the system uses to write numbers. "Base ten" uses ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 . "Base two" makes all of its numbers with only two digits.
We typically use the Hindu numeric system (often called the Hindu-Arabic system in the west). This system can be applied to any base system (binary, octal, hexadecimal, etc) although we predominantly use the decimal (base 10) system in day to day usage.
