Question 1. Calculate the least non-negative residue of 20! mod 23. Also, calculate the least non-negative residue of 20! mod 25. (Hint: Use Wilson’s theorem.) Solution: Since 23 is a prime, by Wilson’s theorem we know that 22! 1 mod 23. Therefore 20!(2122) 1 mod 23. Moreover 21 22 ( 2)( 1) 2 mod 23. Thus: 20! 2 1

You could simply check if the result is negative and then act accordingly: int mod(int n, int m) { int r = n % m; if (r < 0) return r + m; ...

Find the least nonnegative residue of 2(100!) modulo 103 This is what I have so far but dont know where to go form here: 2(100!)

18.10.2011 · Is there an efficient way to get the least non-negative residue modulo n, where n is positive, in C? This is quite easy if the number is non-negative, then it's just a % n (where a is the non-negative integer). However when a is negative, it appears the behaviour, in C89, is implementation defined (thanks kennyTM). I.e. -2 % 11 = -2 or 9.

Find the least nonnegative residue of $5^{18} \mod 11$. To do this I took $5^2 \equiv 3 \mod 11$. Then I did $(5^2)^5 \equiv 3^5 \mod 11$. And $3^5 \equiv 1 \mod 11$. So now I …

5 16 ≡ ( 5 8) 2 ≡ 4 2 ≡ 5 mod 11, and then finally, 5 18 ≡ 5 2 ⋅ 5 16 ≡ 3 ⋅ 5 ≡ 4 mod 11. Also, this should be a much more satisfying answer since the least nonnegative residue of n will always be in the interval [ 0, n]. Share.

Example. Find the least nonnegative residue of 70! (mod 5183). Note: 5183 = 71·73. I’ll start by finding the residues of x= 70! mod 71 and 73. By Wilson’s theorem, x= 70! = −1 (mod 71). Next, let x= 70! (mod 73). Then x= 70! (mod 73) 71·72·x= 70!·71·72 (mod 73) (−2)(−1)x= 72! (mod 73) 2x= −1 (mod 73) Note that 2·37 = 74 = 1 (mod 73). So
