Divisibility Rule of 365

The divisibility rule for 365 is a method by which we can find out if a number is divisible by 365 or not without using the division method. Check whether 730 is divisible by 365 with the divisibility rule.
 

Step 1: Check if the number is divisible by 5. The number 730 ends with a 0, which makes it divisible by 5.

Step 2: Check if the number is divisible by 73. For this, sum the digits of the number (7 + 3 + 0 = 10). Since 10 is not a multiple of 73, 730 is not divisible by 73.

Step 3: Since 730 is not divisible by 73, it is not divisible by 365.
 

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 365.
 

• Know the multiples of 365: Memorize the multiples of 365 (365, 730, 1095, 1460, etc.) to quickly check the divisibility. If the result from the checks is a multiple of 365, then the number is divisible by 365.
   
• Use a calculator for large sums: If the number is large and difficult to compute manually, using a calculator to check divisibility by 73 can be helpful.
   
• Verify with smaller divisors: Since 365 is 5 times 73, first check for divisibility by 5 and then by 73 to verify.
   
• Use the division method to verify: Students can use the division method as a way to verify and cross-check their results. This will help them to verify and also learn.
   

• Divisibility Rule: A set of rules used to find out whether a number is divisible by another number or not.
   
• Multiples: Numbers obtained by multiplying a given number by integers. For example, multiples of 365 are 365, 730, 1095, etc.
   
• Integer: A whole number that can be positive, negative, or zero.
   
• Sum of Digits: The result of adding all the digits in a number together.
   
• Calculator: A tool used to perform mathematical operations more efficiently, especially useful for large numbers.
