Divisibility Rule of 345

The divisibility rule for 345 is a method by which we can find out if a number is divisible by 345 or not without using the division method. Check whether 1035 is divisible by 345 with the divisibility rule.

Step 1: Check if the number is divisible by 5. For 1035, since it ends in 5, it is divisible by 5.

Step 2: Check if the number is divisible by 3. Sum the digits: 1 + 0 + 3 + 5 = 9. Since 9 is divisible by 3, the number is divisible by 3.

Step 3: Check if the number is divisible by 23. Divide 1035 by 23 to verify.

Since 1035 is divisible by 5, 3, and 23, it is divisible by 345.
