Divisibility is the property of being able to divide one number evenly into another without leaving a remainder.
To test for divisibility, there are specific rules or criteria depending on the divisor. The most common ones are:
1. Divisibility by 2: A number is divisible by 2 if it ends in 0, 2, 4, 6, or 8. For example, 568 is divisible by 2 because its last digit is 8.
2. Divisibility by 3: A number is divisible by 3 if the sum of its digits is divisible by 3. For example, 738 is divisible by 3 because 7+3+8=18, and 18 is divisible by 3.
