Divisibility rules are based on the concept of factors and multiples. A number is divisible by another number if the first number is a multiple of the second number. For example, 12 is divisible by 3 because 12 = 4 × 3. To simplify the process, we use divisibility rules, which are based on the last digit or the sum of the digits of a number. For instance, if a number ends in 0 or 5, it's divisible by 5.
