How to Use the Divisibility Test Calculator
Using the divisibility test calculator is simple and straightforward. Here’s a quick step-by-step guide:
- Input the Dividend: Enter the number you want to test for divisibility.
- Input the Divisor: Enter the number by which you want to check divisibility.
- Click the Calculate Button: Hit the button to see the result.
- Review Results: The calculator will display whether the dividend is divisible by the divisor.
Formula for Divisibility Tests
The basic formula for testing divisibility is straightforward: If a number \( A \) is divisible by another number \( B \), then:
A % B = 0
Where % represents the modulus operator. When \( A \) divided by \( B \) has no remainder, \( A \) is considered divisible by \( B \).
Example Calculation
Let’s say we want to test whether 28 is divisible by 4. Here’s how to do it:
- Dividend: 28
- Divisor: 4
- Calculation: 28 % 4 = 0
Since the remainder is 0, we conclude that 28 is divisible by 4.
