2147483647 (or 2^31 - 1) if you're using unsigned ints
If you're using two's complement then it's half that since you're using the first bit for a sign instead.
That would be 216 - 1, or 65535.
1.157920892 x 1077 (rounded)
To get the 2s complement, change all 1 bits to 0s and all 0 bits to 1s, and add 1 to the result. So the 2s complement of the 8-bit binary number 10001011 is the binary integer 01110101. If you want that in decimal, then remember that each place value column is twice the value of the place value column to its right, and the rightmost place value column for an integer is 1. Thus 01110101 in decimal is 64 + 32 + 16 + 4 + 1 = 117 (And 10001011 as a signed 8-bit binary integer represents the decimal integer -117.)
216-1 or (2^16)-1
1. A single bit can represent two different values, 0 and 1. Then simply take the largest of those two possible values, 1, and that's your answer.
(2^32) - 1
Binary Integer
A 5-bit binary counter, interpreted as an unsigned integer, has a range of 0 to 31. Interpreted as a two's complement signed integer, it has a range of -16 to +15.

Largest 8 bit unsigned number is 11111111 binary thus making 255 in decimal.

binary integer don't think so... It's binary digit.
The largest number that can be expressed in six bit binary is 111111, or 63. That however is not prime. Counting down from there, we can see that the first prime below that is 61, which is the answer to the question. Expressed in binary, that would be 111101.
The number of bytes required to store a number in binary depends on the size of the number and the data type used. For instance, an 8-bit byte can store values from 0 to 255 (or -128 to 127 if signed). Larger numbers require more bytes: a 16-bit integer uses 2 bytes, a 32-bit integer uses 4 bytes, and a 64-bit integer uses 8 bytes. Thus, the number of bytes needed corresponds to the number of bits needed for the binary representation of the number.
For an unsigned integer, that would be 216-1. For a signed integer in 2's complement notation, the largest number would be 215-1.
