It is true that the divisibility rules can be very confusing at times. There are a lot of numbers that may not seem divisible by 2 but are still divisible. It would depend on the last number. For example, the number is 4,622. This is divisible by 2 because the last number is an even number.
There are times though when the other numbers will have an effect if the number would still be odd or even. It is best that you get to know more about this. The more that you understand the divisibility rules, the more that you will remember if a certain number is odd or even.
