rem function in ghci changes result when using the Int type

I define this function

congruent_modulo_n a b n = (rem a n) == (rem b n)

If the signature is:

congruent_modulo_n :: Integer->Integer->Integer->Bool

Then when I try this function in the ghci everything works perfect. If I use this signature:

congruent_modulo_n :: Int->Int->Int->Bool

Then for the following input I get False:

congruent_modulo_n (3^(113-1)) 1 113
