It is 15.
It depends upon the base of the number, but it is always one less than the base. For decimal numbers (base 10), our usual numbers, the largest digit that can be used in 10 - 1 = 9.
It is 888 which, in decimal equivalent, is 728.
Because - Hex is an exact multiple of binary - whereas decimal numbers need to be converted from base 10 to base 2.
The binary number 1000 is the decimal (base 10) number 8. The digits in a binary number are exponents of 2 rather than 10, so that for a four-digit number in binary, the digit places represent 8, 4, 2, 1 1000 (binary) = 8 + (0x4) + (0x2) + (0x1) = 8
The greatest value a digit can have in base for is 3. Thus the largest three-digit number in base for would be 333. In base 10, this number is 3x16 + 3x4 + 3 = 63 Therefore 63 is the largest digit that would be three digits in base 4.
12^3-1=1727
The largest 4 digit number in base 8 is 77778 (= 409510).
666 - which in base 10 would be 294+42+8=344
It is 15.
999.
It is 15.
A three digit number cannot be divisible by a 5 digit number - in any base.
222
There would need to be a digit which represents Ten. This would be the largest digit. Any number can be represented in any number-base system, so there is no 'largest number' just largest digit. Base eleven is not commonly used as some of the others (like hexadecimal, which uses letters A-F to represent ten through fifteen). You could use A for ten or maybe you want to use X (like roman numeral ten).
That depends on what base you are using. It could be 1
