Divisibility Rule of 555

The divisibility rule for 555 is a method by which we can find out if a number is divisible by 555 or not without using the division method. Check whether 1665 is divisible by 555 with the divisibility rule.

Step 1: Check if the number is divisible by 5. Since the last digit of 1665 is 5, it is divisible by 5.

Step 2: Check if the number is divisible by 3. Sum the digits: 1 + 6 + 6 + 5 = 18. Since 18 is divisible by 3, 1665 is divisible by 3.

Step 3: Check if the number is divisible by 37. Divide 1665 by 37. If it results in an integer, it is divisible by 37.

Since 1665 is divisible by 5, 3, and 37, it is divisible by 555.
