The number 31 (decimal) can be represented as a binary number this way: 11111 ...which is 1 + 2 + 4 + 8 + 16 = 31 Note the number 31 is one less than a power of two. Numbers like that are always strings of 1's for binary digits.
It can!The difference between 31/2 and 31/3, for example, is 1/6 which is less than 1.
The natural numbers are the counting numbers. Therefore, the natural numbers less than 31 are the numbers from 1 to 30.
the result is a number less than the original number
1, 11, 21, 31, 41. 1 is not a prime number.

11, 31, 41, 61, 71
When the number is between 0 and 1, or less than -1
The natural numbers are the counting numbers. Therefore, the natural numbers less than 31 are the numbers from 1 to 30.
1, because 31 is a prime number, and so there will be no number which divides into it other than 31 and 1.
the result is a number less than the original number
