Divisibility Rule of 666

The divisibility rule for 666 is a method by which we can find out if a number is divisible by 666 or not without using the division method. Check whether 1998 is divisible by 666 with the divisibility rule.

Step 1: Check the divisibility of the number by 2. Since 1998 ends in 8, which is even, it is divisible by 2.

Step 2: Check the divisibility by 3 by adding the digits. The sum of the digits of 1998 is 1 + 9 + 9 + 8 = 27, which is divisible by 3.

Step 3: Check the divisibility by 37. Divide 1998 by 37. Since 1998 ÷ 37 = 54, which is an integer, it is divisible by 37.

Since 1998 is divisible by 2, 3, and 37, it is divisible by 666 (since 666 = 2 × 3 × 37).

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 666.

• Know the factors of 666: Memorize the factors of 666 (2, 3, 37) to quickly check the divisibility.
