Basically, Divisibility rules are classified into two groups
Root numbers and Non root numbers
Root numbers know simply as prime number like 2,3,5,7,11
Other than the roots words are called Non root numbers or non prime number
I will clearly explain this root words after the learning the divisibility rules of the Root numbers
Divisibility Rule of ''2'':
When a number is divisible by 2 then the last digit of the number must be divisible by 2
For example : 64
In the above number last digit is "4" which is a multiple of 2 .Clearly, we can say that the above number 64 is divisible by 2
Normal checking: 64/2=32
The above statement is verified
