Divisibility Rule of 662

The divisibility rule for 662 is a method by which we can determine if a number is divisible by 662 or not without using the division method. Check whether 1986 is divisible by 662 using the divisibility rule.

Step 1: Divide the number into groups that align with the factors of 662. The factors of 662 are 2, 331, and 1. First, check divisibility by 2.

Step 2: Since 1986 is even, it is divisible by 2. Now, check divisibility by 331.

Step 3: To check, perform the division of 993 (1986 divided by 2) by 331. If the result is a whole number, then 1986 is divisible by 662.

Step 4: Since 993 divided by 331 equals 3, which is a whole number, 1986 is divisible by 662.

• Know the factors of 662: Memorize that 662 is divisible by 2 and 331. Check divisibility by these factors to determine if the number is divisible by 662.
   
• Use the divisibility rule of smaller factors: Start by checking smaller factors like 2 before moving to larger factors like 331 for easier calculations.
   
• Repeat the process for large numbers: For large numbers, repeat the divisibility test for each factor until you confirm divisibility by 662.
   
• Use the division method to verify: Students can use the division method to verify and crosscheck their results. This will help them to confirm and also learn.
