Relevant wiki: Chinese Remainder Theorem
Let the required integer be N . We can find N using the Chinese remainder theorem as follows:
N ⟹ 2 k + 1 2 k ⟹ 6 m + 1 m ⟹ 3 0 n + 7 2 n ⟹ 2 1 0 p + 6 7 p + 1 p ≡ 1 (mod 2) ≡ 1 (mod 3) ≡ 0 (mod 3) ≡ 2 (mod 5) ≡ 1 (mod 5) ≡ 4 (mod 7) ≡ 4 (mod 7) ≡ 3 (mod 11) ≡ 3 (mod 11) ≡ 2 (mod 11) ⟹ N ≡ 2 k + 1 , where k ∈ Z ⟹ k = 0 ⟹ N ≡ 2 × 3 m + 2 k + 1 ⟹ m = 1 ⟹ N ≡ 6 × 5 n + 6 m + 1 ⟹ n = 2 ⟹ N ≡ 3 0 × 7 p + 3 0 n + 7 ⟹ p = 2
Therefore, N ≡ 2 1 0 × 2 + 6 7 = 4 8 7
