The divisibility rule for two states that any number with the last digit of 0, 2, 4, 6, or 8 will be divisible by 2. Simply put, any even number is divisible by 2.
If the sum of the digits of a number is divisible by 3, then the number is divisible by 3. Some examples of numbers divisible by 3 are as follows. The number 85203 is divisible by 3 because the sum of its digits 8+5+2+0+3=18 is divisible by 3.
The basic rule for divisibility by 4 is that if the number formed by the last two digits in a number is divisible by 4, the original number is divisible by 4; this is because 100 is divisible by 4 and so adding hundreds, thousands, etc. is simply adding another number that is divisible by 4.
A number is divisible by 6 if it is divisible by 2 and 3 both. Consider the following numbers which are divisible by 6, using the test of divisibility by 6: 42, 144, 180, 258, 156. [We know the rules of divisibility by 2, if the unit's place of the number is either 0 or multiple of 2].
If the last three digits of a number are divisible by 8, then the number is completely divisible by 8.divisibililty rule of 8
The rule for divisibility by 9 is similar to divisibility rule for 3. That is, if the sum of digits of the number is divisible by 9, then the number itself is divisible by 9.divisibililty rule of 9.
Divisibility rule for 10 states that any number whose last digit is 0, is divisible by 10.divisibililty rule of 10
If the difference of the sum of alternative digits of a number is divisible by 11, then that number is divisible by 11 completely.divisibililty rule of 11.
