Beginner Explanation
Divisibility tests are quick checks to determine whether one integer is evenly divisible by another without performing full division. For example, a number is divisible by 2 if its last digit is even, by 5 if it ends in 0 or 5, and by 10 if it ends in 0. These simple rules rely only on examining the digits.
