class 8th math Divisibility Rule 1- The divisibility rule for 2 The rule says that any number that ends in a 0, 2, 4, 6, or 8 can be divided by 2 to produce a whole number. All even numbers (numbers that always end in 0, 2, 4, 6 or 8) are divisible by 2. for eg- 12,24, 30,74, 88, 502 etc 2- The d ivisibility Rule for 3 If the sum of all digits of that whole number is Divisible by 3 then that number is also divisible by 3 eg- 63 6+3=9 9 is divisible by 3 hence 63 is also divisible by 3 eg- 582 5+8+2 =15 15 is divisible by 3 hence 582 also divisible by 3 3- The divisibility rule for 4 If the number formed by digits at tens place and ones place is divisible by 4 then that whole number also divisible by 4 eg- 164 tens and ones place num is 64 64 is divisible by 4 hence 164 also divisible by 4 eg 5564, 34564, 2355616,786656,97875616 etc 4- The divisibility rule for 5 If the last digit of any number is 0 or 5 then that number is divisible by 5 eg- 25 , 300 ,567775
