SpletBut how do we mathematically establish the statement there are more primes p≡3 (mod 4) than primes p≡1 (mod 4)? According to the Prime Number Theorem of Hadamard/de la Vallee´ Poussin, lim x→∞ π(x;4,3) π(x;4,1) = 1 (1.2) that says there are asymptotically an equal number of primes in both residue classes as x→∞. SpletThis is our answer: the multiplicative inverse of 11 modulo 26 is 19. Verification Let's call the answer we just found i (i as in inverse). We can check that we found the right answer by verifying that i × b ≡ 1 (mod n): So b=11, n=26 and i=19. Then i × b (mod 26) ≡ 19 × 11 (mod 26) ≡ 209 (mod 26) ≡ 1 mod (26). 209 ≡ 1 (mod 26) fish stores in ma
