Divisibility Rule of 355

The divisibility rule for 355 is a method by which we can find out if a number is divisible by 355 or not without using the division method. Check whether 710 is divisible by 355 with the divisibility rule.

Step 1: Divide the number into groups of three digits from right to left. Here, 710 only has one group: 710.

Step 2: Check if each group is divisible by 355. In this case, 710 ÷ 355 = 2, which is a whole number.

Step 3: Since 710 is divisible by 355, the number is divisible by 355. If the result is not a whole number, then the number isn't divisible by 355.

Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 355.

Know the multiples of 355:  

Memorize the multiples of 355 (355, 710, 1065…etc.) to quickly check divisibility. If the result from division is a whole number, then the number is divisible by 355.

Use estimation:  

If the number is large, estimate whether it seems close to a multiple of 355 before checking exact divisibility.

Repeat the process for larger numbers:  

Students should keep repeating the divisibility process with larger numbers by breaking them into three-digit groups.

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.

• Divisibility Rule: The set of rules used to find out whether a number is divisible by another number or not.

• Multiples: The results obtained after multiplying a number by an integer. For example, multiples of 355 are 355, 710, 1065, etc.

• Integer: Numbers that include all whole numbers, negative numbers, and zero.

• Estimation: A method of making an educated guess about the value or size of something, often used to simplify calculations.

• Remainder: The amount left over after division when one number does not divide the other exactly.
