**3 Frequently Asked Questions About Modular Arithmetic**

(a) The objective is to find the order of integers 2, 3, and 5 modulo : Let be an integer, , with , then the order of modulo is defined by, the smallest positive integer such that .... Finding the order of a (mod m) Here m > 1 and gcd(a,m)=1. See MP313 lecture notes. This is a BCMATH conversion of a BC program.

Cathy Frey 13,090 views. 11:22... Say I wish to find the order of 2 modulo 41. The way I've been shown to compute this is to literally write out $2^k$ and keep going upwards with $0 \leq k \leq 41$, or until I observe periodicity in the sequence, and then state the order from there.

The same rules of associativity and commutativity apply under modular multiplication, so we don't need to worry about the order we write the terms in our expressions and we don't need to use brackets (unless we choose to). The two axioms G1 and G3 require some further explanation.... @Wiwat, that is true, but how do you find at least one generator. He is asking given any prime p, find a primitive root modulo p. He is asking given any prime p, find a primitive root modulo p. 4

## How To Find The Order Of Modulo

### For a positive integer n, two integers a and b are said to be congruent modulo n (or a is congruent to b modulo n), if a and b have the same remainder when divided …

- 24/10/2010 · Here is the question from the book: Determine a primitive root modulo 19, and use it to find all the primitive roots. [tex]\varphi(19)= 18[/tex] And 18 is the order of 2 modulo 19, so 2 is a primitive root modulo 19, but I am not sure of how to use that to find all primitive roots modulo …
- As with order, the concept of primitive roots also extends to residue classes. Thus, g is a primitive root modulo n if and only if every integer in [g]n is too. Accordingly, we use the word distinct or incongruent primitive roots modulo n when we mean that they belong to di?erent residue classes. So, to search for a primitive root modulo n it su?ces to look at a reduced residue system
- Overview. Modular arithmetic is simply arithmetic that is restricted to a finite set of elements. For our purposes, that set of elements will be the set of all non-negative integers less than some integer n (greater than 1) where n is called the modulus of the set.
- The Chinese remainder theorem is a theorem of number theory, which states that if one knows the remainders of the Euclidean division of an integer n by several integers, then one can determine uniquely the remainder of the division of n by the product of these integers, under the condition that the divisors are pairwise coprime.
