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 … WebDec 8, 2016 · Find the solution to the simultaneous congruences. x ≡ 17 (mod 37) x ≡ 9 (mod 17) x ≡ 6 (mod 7) congruences; chinese-remainder-theorem; Share.

WebAug 1, 2024 · Solution 2. The 3, 2, 1 are from the right hand side of your congruences. We know that x = 3 is a solution to the first congruence, but this doesn't work as a solution to the next 2 congruences. So Chinese remaindering tells you to compute (3 ⋅ 5) − 1 = 15 − 1 mod 7. You find that this is 1 (since 15(1) + ( − 2)7 = 1 ). WebDecide whether the system has a solution (and if it does, nd all solutions) by solving the system for each prime factor separately. 1. n2 11 (mod 35) Working over each prime factor separately gives n2 1 (mod 5) and n2 4 (mod 7), so n = 1 (mod 5) and n = 2 (mod 7).
WebAug 9, 2024 · Apply prime factorization to each of the moduli n, omit common factors, proceed in much the way you did for (a), and transform each statement in the system into equivalent congruences for the prime powers: (i.e. to a prime residue system ). E.g. x ≡ 3 ( mod 10) x ≡ 3 ( mod 2) and x ≡ 3 ( mod 5). And of course, you'll then want to use the ...
