The number 1 is a divisor of every number.
Explanation
Divisibility means that when you divide a number by its divisor, the result is a whole number (an integer) with no remainder. Because any number divided by 1 equals itself, every number is divisible by 1.
For example:
- 5 / 1 = 5
- 100 / 1 = 100
- -7 / 1 = -7
- 0 / 1 = 0
In each case, the result is a whole number.
It's also important to note that every number is divisible by itself. For example, 5 / 5 = 1, 100 / 100 = 1, etc. However, the original question specifically asks for one number that every number is divisible by, which is 1.
