Understanding Divisibility Tests
A divisibility test is a shortcut to determine whether a number is divisible by another number without performing long division, usually by examining its digits. For example, a number is divisible by 2 if its last digit is even, and by 5 if its last digit is 0 or 5. Divisibility tests are very useful in number theory and simplify calculations. They help in factoring numbers and understanding number properties. This tool helps you quickly check divisibility for any two given numbers.
- Divisible: A number is divisible by another if the remainder after division is zero.
- Divisor: The number by which another number is divided.
- Quotient: The result of the division.
- Remainder: The amount left over after division. In divisibility tests, we check if the remainder is 0.
