i don't know help
There are 151 3-digit numbers that are divisible by 6.
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.
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.
All 4 digit numbers that are divisible by 9 are also divisible by 3. The first is 1008 and the last is 9999.

Select all the numbers that $4221462$ is divisible by.
None. Extremely simple proof: To be divisible by 5 the units digit must be 5. But then it would not be divisible by 2.
3, 6, 9
Trick question all numbers are divisible by four ,but only 175 result in whole numbered answers
