Divisibility Rule of 202
The divisibility rule is a way to find out whether a number is divisible by another number without using the division method. In real life, we can use the divisibility rule for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 202.
What is the Divisibility Rule of 202?
The divisibility rule for 202 is a method by which we can find out if a number is divisible by 202 or not without using the division method. Check whether 40404 is divisible by 202 with the divisibility rule.
Step 1: Look for a pattern or a method specific to 202. Since 202 is 2 × 101, check if the number is divisible by both 2 and 101.
Step 2: Ensure the last digit is even for divisibility by 2. In 40404, the last digit is 4, which is even.
Step 3: For divisibility by 101, separate the number into pairs from the right and add them. If the result is divisible by 101, then the whole number is divisible by 101.
Example: For 40404, split into pairs: 04 and 040. Add them: 4 + 40 = 44. Since 44 is not divisible by 101, 40404 is not divisible by 202.
