Divisibility Rule of 211

The divisibility rule for 211 is a method by which we can determine if a number is divisible by 211 without using the division method. Let's check whether 4211 is divisible by 211 using the divisibility rule.

Step 1: Multiply the last digit of the number by 2, here in 4211, 1 is the last digit, multiply it by 2. 1 × 2 = 2.

Step 2: Subtract the result from Step 1 from the remaining values, excluding the last digit. i.e., 421–2 = 419.

Step 3: Divide the result from step 2 by 211. If the quotient is an integer, then the original number is divisible by 211. Here, 419 ÷ 211 does not yield an integer, so 4211 is not divisible by 211.
 

Learning divisibility rules will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 211.

Know the multiples of 211:

Memorize the multiples of 211 (211, 422, 633, 844, etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 211, then the number is divisible by 211.
