Divisibility Rule of 157

The divisibility rule for 157 is a method by which we can find out if a number is divisible by 157 or not without using the division method. Check whether 471 is divisible by 157 with the divisibility rule.

Step 1: Calculate the remainder when the last three digits are divided by 157. In 471, the last three digits are 471 itself. The remainder when 471 is divided by 157 is 0, as 471 is exactly three times 157.

Step 2: If the remainder is 0, then the number is divisible by 157. Therefore, 471 is divisible by 157.
 

Learning divisibility rules will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 157.

• Know the multiples of 157: Memorize the multiples of 157 (157, 314, 471, 628, etc.) to quickly check divisibility. If the result of the division is a multiple of 157, then the number is divisible by 157.
   
• Use large numbers: If the number is large, calculate the remainder of the last three digits when divided by 157. If needed, use this method repeatedly by breaking down the number into smaller parts.
   
• Verify with the division method: Students can use the division method to verify and cross-check their results. This will help them verify and also learn.
   

• Divisibility rule: The set of rules used to find out whether a number is divisible by another number or not. For example, a number is divisible by another if it leaves a remainder of 0 after division.
   
• Multiples: Multiples are the results we get after multiplying a number by an integer. For example, multiples of 157 are 157, 314, 471, 628, etc.
   
• Remainder: The remainder is the amount left over after division when one number doesn't divide the other exactly.
   
• Division: Division is a mathematical operation where a number is divided into equal parts.
   
• Integer: An integer is a whole number that can be positive, negative, or zero.
