1. Hey guys, using algebra, is there anyway to find out a number that is a square, a multiple of 4 and 7 and odd?
2. An integer that is a multiple of 4 is not odd.

I've always thought 4444 is a rather odd number
4. Any even number squared is a muliple of 4 (see if you can prove it) and any odd number squared is odd. And for a square number to be a multiple of 7, it's square root needs to be a multiple of 7 (why?).
