like N=5053=163*31 and N=169*37=6253 if we do not know the factors and if we do not want to factor them. They both have the same last two digits.
I can't think of any test to apply to this kind of numbers ( it's in fact a family of numbers that share the same last two digits but are product of (last digit only ) 3*1 or 7*9 ).
