I am a 3 digit number divisible by 7 but not 2 the sum of my digits is 4 what number am I
If the number formed by the last three digits is divisible by 8. This requires that: if the digit in the hundreds place is even, the last two digits must form a number divisible by 8 and if the digit in the hundreds place is odd, the last two digits must form a number divisible by 4 but not by 8.
If the last two digits are divisible by 4 then the number is divisible by 4. Thus, if the tens digit is even and the units digit is 0 or 4 or 8 OR if the tens digit is odd and the units digit is 2 or 6 then the number is divisible by 4.
A number divisible by 123456789 must be 0 or bigger than 123456789. It must, therefore have 1 digit or 9 digits (or more). A remainder of 1 makes no difference to the number of digits. In any case, there can be no number of 4 digits that is divisible by 123456789.
the answer is 95

There is no number, no matter the number of digits, that is only divisible by 2.
If the number formed by the last three digits is divisible by 8. This requires that: if the digit in the hundreds place is even, the last two digits must form a number divisible by 8 and if the digit in the hundreds place is odd, the last two digits must form a number divisible by 4 but not by 8.
When its digital root is 9 (divisible by 9) and it is even (divisible by 2). The digital root of a number is calculated by adding up all the digits in a number. If the answer is greater than 9, then repeat until you get an answer that is a single digit.
4 and all of its multiples are divisible by 4. They end in even digits. No number that ends in an odd digit is divisible by 4.

Any 5-digit number is greater than a 4-digit one.
If the last two digits are divisible by 4 then the number is divisible by 4. Thus, if the tens digit is even and the units digit is 0 or 4 or 8 OR if the tens digit is odd and the units digit is 2 or 6 then the number is divisible by 4.
A number divisible by 123456789 must be 0 or bigger than 123456789. It must, therefore have 1 digit or 9 digits (or more). A remainder of 1 makes no difference to the number of digits. In any case, there can be no number of 4 digits that is divisible by 123456789.
the answer is 95
The 2-digit multiples of 11 all have identical digits.
