Divisibility Rule of 601

The divisibility rule for 601 is a method by which we can find out if a number is divisible by 601 or not without using the division method. Check whether 1202 is divisible by 601 with the divisibility rule.  
Step 1: Split the number into two parts: the last three digits and the rest. Here in 1202, 202 is the last three digits.
Step 2: Subtract the last three digits from the remaining part. i.e., 1 - 202 = -201.
Step 3: Determine if the result is a multiple of 601. If the result from step 2 is a multiple of 601, then the number is divisible by 601. If not, the number isn't divisible by 601.

Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 601.

Know the multiples of 601: Memorize the multiples of 601 (601, 1202, 1803, 2404…etc.) to quickly check the divisibility. If the result from the subtraction is a multiple of 601, then the number is divisible by 601.

Use the negative numbers: If the result we get after the subtraction is negative, we will avoid the negative sign and consider it as positive for checking the divisibility of a number.

Repeat the process for large numbers: Students should keep repeating the divisibility process until they reach a small number that is divisible by 601. 

Use the division method to verify: Students can use the division method as a way to verify and crosscheck their results. This will help them to verify and also learn.
