Congruence modulo examples

  • say “a is congruent to r modulo m”). Congruence modulo a natural number m is an equivalence relation on the set of natural numbers. This means that the set R := { (a, b) | a ≡ b mod m }
Congruence. Let n be a positive integer. We say two integers are congruent "modulo n" if they differ by a multiple of the integer n. For example, if n = 5 we can say that 3 is congruent to 23...

For example, if n = 5 we can say that 3 is congruent to 23 modulo 5 (and write it as 3 23 mod 5) since the integers 3 and 23 differ by 4x5 = 20. The statement a b (mod n) is equivalent to the statements “a - b is a multiple of n” or “a - b is divisible by n”.

    The Multiplicative Group of Integers modulo p Theorem. Let p be a prime integer. The multiplicative group F× p of nonzero congruence classes modulo p is a cyclic group. A generator for this cyclic group is called a primitive element modulo p. The order of F× p is p − 1, so a primitive element is a nonzero congruence class whose order in F×

    Example 2. In modulo 10, what is 19,374 · 3,172? One way to attempt this problem is to multiply out these numbers and then find the remainder when dividing by 10. However, since we want our answer in modulo 10, we can instead multiply just the representatives from their congruence classes.

    Dec 21, 2020 · The integer a could be congruent to 0,1, 2,..., or n - 1 modulo n. For example, if we assume that 5 does not divide an integer a, then we know a is not congruent to 0 modulo 5, and hence, that a must be congruent to 1, 2, 3, or 4 modulo 5. We can use these as 4 cases within a proof.

    Dec 22, 2020 · $\begingroup$ This is the basic number theory ( congruence class) that after the congruence is thought no one is using the brackets ( only if there is a real distinction is required). Note that sometimes for efficiency we allow to use the number represented other than the least residue system modulo n.

The next results show that congruence behaves the same way as equality with respect to addition and multiplication, and the rst theorem shows when congruence of two integers modulo m > 1 implies that the
