What are the rules of divisiblety?

Answer 1

The rules of divisibility are simple guidelines to determine if a number can be divided by another without a remainder. For example, a number is divisible by 2 if its last digit is even, by 3 if the sum of its digits is divisible by 3, by 5 if it ends in 0 or 5, and by 10 if it ends in 0. Other common rules include divisibility by 4 (if the last two digits form a number divisible by 4) and by 6 (if it’s divisible by both 2 and 3). These rules provide quick ways to check for factors without performing full division.
