When the last digit is zero. All whole numbers of more than one digit and with a last digit of 0, 2, 4, 5, 6 or 8 are divisible by another number. Numbers ending with the other digits, 1, 3, 7 and 9, might be divisible by another number, and they might not.
A whole number is evenly divisible by 10 only if its last digit is a zero.
No. A whole number is (evenly) divisible by 10 only if its last digit is ' 0 '.

No, any whole number ending in a digit divisible by 2 is also divisible by 2 and therefore not a prime number.
18 numbers are there
If the last digit doubled subtracted from the rest is a multiple of 7, the whole number is divisible by 7.
If the number is even, it's divisible by 2. If the sum of the digits is a multiple of 3, the whole number is divisible by 3. If the last two digits are a multiple of 4, the whole number is divisible by 4. If the last digit is a 0 or a 5, the whole number is divisible by 5. If the number is even and divisible by 3, it's divisible by 6. If the last digit doubled subtracted from the rest is a multiple of 7, the whole number is divisible by 7. If the last three digits are a multiple of 8, the whole number is divisible by 8. If the sum of the digits is a multiple of 9, the whole number is divisible by 9. If the number ends in 0, it's divisible by 10.
Yes. If the last digit is even (ie one of 0, 2, 4, 6, 8) then the whole number is divisible by 2. The last digit is 4, so the number is divisible by 2.
Double the last digit, subtract it from the rest. If the result is divisible by 7, the whole number is divisible by 7.
If you double the last digit and subtract it from the rest of the number and the answer is zero or divisible by 7, then the whole number is divisible by 7.
If the last digit doubled subtracted from the rest is a multiple of 7, the whole number is divisible by 7.
That would be the same as the smallest four-digit even number: 1,000, which also happens to be the smallest four-digit whole number.
