Divisibility Rule of 815

The divisibility rule for 815 is a method by which we can find out if a number is divisible by 815 or not without using the division method. Check whether 2445 is divisible by 815 with the divisibility rule.  

Step 1: Divide the number into parts that are easier to manage. In 2445, consider its components for simplification.

Step 2: Since 815 can be expressed as 5 × 163, check divisibility by 5 and 163.

Step 3: A number is divisible by 5 if its last digit is 0 or 5, and 2445 ends with 5.

Step 4: For divisibility by 163, use the division method to check if 2445 is divisible by 163.

Step 5: After confirming divisibility by both 5 and 163, conclude that 2445 is divisible by 815.
