Formula Used in “Chinese Remainder Theorem Calculator”

The Chinese Remainder Theorem (CRT) provides a method for solving systems of simultaneous congruences with different moduli. This theorem is particularly useful in number theory and computer science. The standard formula used in the Chinese Remainder Theorem is expressed as follows:

Formula:

Given a system of congruences:

  • x ≡ a₁ (mod m₁)
  • x ≡ a₂ (mod m₂)
  • x ≡ a₃ (mod m₃)
  • …
  • x ≡ aₖ (mod mₖ)

The solution is given by:

x ≡ (Σ (aᵢ * Nᵢ * yᵢ)) (mod N)

Where:

  • N = m₁ * m₂ * m₃ * … * mₖ

Step-by-Step Breakdown of the Formula

To effectively utilize the Chinese Remainder Theorem, it’s essential to understand each variable and the calculation process:

  1. N: The product of all moduli mᵢ
  2. aᵢ: The remainders from each congruence.
  3. Nᵢ: The value of N / mᵢ
  4. yᵢ: The modular multiplicative inverse of Nᵢmᵢ
  5. x: The final solution modulo N

Example Calculation

Let's solve a system of congruences using the Chinese Remainder Theorem:

  • x ≡ 2 (mod 3)
  • x ≡ 3 (mod 4)
  • x ≡ 1 (mod 5)
Step-by-Step Calculation
  1. Calculate N:
    N = 3 * 4 * 5 = 60
  2. Calculate each Nᵢ:
    • N₁ = N / m₁ = 60 / 3 = 20
    • N₂ = N / m₂ = 60 / 4 = 15
    • N₃ = N / m₃ = 60 / 5 = 12
  3. Compute each yᵢ:
    • y₁ = 20 mod 3 = 2 (since 20 * 2 ≡ 1 mod 3)
    • y₂ = 15 mod 4 = 3 (since 15 * 3 ≡ 1 mod 4)
    • y₃ = 12 mod 5 = 3 (since 12 * 3 ≡ 1 mod 5)
  4. Combine the results:
    x ≡ (2*20*2 + 3*15*3 + 1*12*3) mod 60
  5. This simplifies to:
    x ≡ (80 + 135 + 36) mod 60
  6. Calculate x:
    x ≡ 251 mod 60 -->
    x ≡ 11
