Some quick rules to test divisibility for the whole number :
Divisible by 2 : if last digit is even (0,2,4,6,8)
Divisible by 3 : if the sum of the digits is divisible by 3 (378 = 3+7+8) = 18 = 18/3 = 6)
Divisible by 4 : if the last 2 digits are divisible by 4
Divisible by 5 : if the last digit is 0 or 5
Divisible by 6 : if number is even and the sum of the digits is divisible by 3(Divisible by 3 rule)
Divisible by 7 : if the result is divisible by 7 (Double the last digit and subtract it from a number made by rest of digits : 665 = 66 - 5#2 : 66 - 10 : 56 : 56/7 = 8
Divisible by 8 : if the last three digits are divisible by 8
Divisible by 9 : if the sum of the digits is divisible by 9
Divisible by 10: if the last digit is 0
