hello @cbcao263
u are not checking coprime correclty.
if a%b!=0 is not sufficient condition for coprime.
for example
4, 6
6%4!=0 , but they are not coprime .right ?
because 2 is a common factor for them.

solution for this problem is ->
print any three consecutive number (but starting element should be even)
a, a+1,a+2 where a should be even
