Please, Implement the Chinese Remainder Theorem. Allowing at least 3 pairwise relatively prime positive integers.
p1: x = 2 (mod 3)
p2: x = 3 (mod 5)
p3: x = 2 (mod 7)
From p1, x = 3t + 2, for some integer t. Substituting this into p2 gives 3t = 1 (mod 5). Looking up 1/3 in the division table modulo 5, this reduces to a simpler equation
p4: t = 2 (mod 5)
which, in turn, is equivalent to t = 5s + 2 for an integer s. Substitution into x = 3t + 2 yields x = 15s + 8. This now goes into p3: 15s + 8 = 2 (mod 7). Casting out 7 gives s = 1 (mod 7). From here, s = 7u + 1 and, finally, x = 105 u& + 23.
Note that 105 = lcm(3, 5, 7). Thus we have solutions 23, 128, 233, ...
