What is an integer? A simple definition of integers is they are positive and negative numbers along with zero. Integers are not fractional numbers. For example, -10, -5, 0, 5, 10, etc. are integers.
Examples of negative integers are -1, -2, -3, and -4. The number 0 is also considered an integer even though it has neither a positive or negative value. In most programming languages, you can convert a number into an integer using the int function....

If you're trying to find amicable pairs, or computing the sum of divisors for many numbers, then separately factorising each number (even with the fastest possible algorithm) is absolutely an inefficient way to do it. The sum-of-divisors function, σ(n) = (sum of divisors of n), is a...
