What is the Divisibility Rule of 865?

The divisibility rule for 865 is a method by which we can find out if a number is divisible by 865 or not without using the division method. Check whether 1730 is divisible by 865 with the divisibility rule.  


Step 1: Recognize that a number is divisible by 865 if it is divisible by the prime factors of 865: 5, 173.


Step 2: Check divisibility by 5 by seeing if the number ends in 0 or 5. Since 1730 ends in 0, it is divisible by 5.


Step 3: Check divisibility by 173 by performing the actual division or using a calculator, as there isn't a simple rule for 173.


Step 4: If the number is divisible by both 5 and 173, it is divisible by 865. In this case, 1730 is divisible by 5 and 173, so it is divisible by 865.divisibility rule of 865
