If the units digit is zero, then you have an even number ...
' 2 ' must be one of its factors.
It must also have two or more places ... it's greater than 9.
If it had only one place, and its units digit were zero, then
the whole thing would be zero.
Since it has two or more places, 5 and 10 are also factors.
