WebFeb 10, 2024 · x ≡ a₁ (mod n₁). We look back at the equations we had and input accordingly: a₁ = 1, n₁ = 3. Similarly, for the other two congruences, we get: a₂ = 2, n₂ = 4, a₃ = 3, n₃ = 5. Once we give the last number, the Chinese remainder theorem calculator will spit out the … WebOct 23, 2010 · In modern number theory, we would write that as a problem to solve the simultaneous congruences x ≡ 2 (mod 3) x ≡ 3 (mod 5) x ≡ 2 (mod 7) The Chinese Remainder Theorem (CRT) tells us that since 3, 5 and 7 are coprime in pairs then there is a unique solution modulo 3 x 5 x 7 = 105. The solution is x = 23.
