All even numbers (they end in 0,2,4,6 or 8) are divisible by 2
Not all of them are.
Even numbers are divisible by two, and half of all numbers are even, so there is a 50 percent chance that a four-digit number is divisible by two.

All 4 digit numbers that are divisible by 9 are also divisible by 3. The first is 1008 and the last is 9999.
Using the tests for divisibility:Divisible by 3:Add the digits and if the sum is divisible by 3, so is the original number: 2 + 3 + 4 = 9 which is divisible by 3, so 234 is divisible by 3Divisible by 6:Number is divisible by 2 and 3: Divisible by 2:If the number is even (last digit divisible by 2), then the whole number is divisible by 2. 234 is even so 234 is divisible by 2.Divisible by 3:Already shown above to be divisible by 3. 234 is divisible by both 2 & 3 so 234 is divisible by 6Divisible by 9:Add the digits and if the sum is divisible by 9, so is the original number: 2 + 3 + 4 = 9 which is divisible by 9, so 234 is divisible by 9Thus 234 is divisible by all 3, 6 & 9.
Select all the numbers that $4221462$ is divisible by.
3, 6, 9
None. Extremely simple proof: To be divisible by 5 the units digit must be 5. But then it would not be divisible by 2.
Trick question all numbers are divisible by four ,but only 175 result in whole numbered answers
