Section 4.1 Divisibility and Modular Arithmetic 87 CHAPTER 4 Number Theory and Cryptography SECTION 4.1 Divisibility and Modular Arithmetic 2. a) 1 | a since a = 1 · a. b) a | 0 since 0 = a · 0. 4. Suppose a | b ‚ so that b = at for some t ‚ and b | c‚ so that c = bs for some s. Then substituting the first equation into the second‚ we obtain c = (at)s = a(ts). This means that a | c‚ as desired. 6. Under the hypotheses‚ we have c = as and d = bt for some s and t . Multiplying

------------------------------------------------- Prime number A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number. For example 5 is prime‚ as only 1 and 5 divide it‚ whereas 6 is composite‚ since it has the divisors 2 and 3 in addition to 1 and 6. The fundamental theorem of arithmetic establishes the central role of primes in number theory: any integer greater

triggered off the ‘chain of movement’. The Prime Mover is the ‘Uncaused First Cause’‚ both the unmoved mover and the final cause. As a result this means that all of earth and existence is in a constant stage of movement and change.‚ Aristotle is similar in his thinking to just like another philosopher‚ Heraclitus‚ who believed everything is in a dramatic state of change and‚ that this change had to be started by someone he called ‚ the Prime Mover. The Prime Mover started off a cosmic chain of movement

It is in the Name of Optimus Prime When some people think of a hero‚ what comes to mind is Optimus Prime. In the film Transformers‚ Prime is all about power and leadership. Although faced with overwhelming forces of evil from the Decepticons‚ Optimus Prime surpasses the expectations of his enemies and displays hero‚ warrior‚ and chief character archetypes in protecting the planet earth from absolute destruction.

Gems from the world of data structures and algorithms Bit-Sum Prime Difficulty level: moderate Every student‚ who has learned programming‚ must have written a program to determine whether a given positive integer is a prime number. Basically in order to determine whether a positive integer n is prime‚ we search for any number in the range [2‚ n − 1] which can divide n. Some of you would have designed a slighly better implementation where you search √ for any divisor of

What are the major advantages of the use of books of prime entry? There are many major advantages of using prime entry for varying entries. The first advantage is that it helps to keep the records briefly as it is difficult to manage every single transaction in the main ledger as it occurs. Another advantage of using prime entry of accounting makes it easy to follow transactions and avoids the confusion occur if all of the different information was in one place. The separated information saves the

published his paper “On The Number of Primes Less Than a Given Magnitude”‚ in which he defined a complex variable function which is now called the Riemann Zeta Function(RZF). The function is defined as: ζ(s) = Σ 1 ns (1.1) Where n ranges over the positive integers from 1 to infinity and where s is a complex number. To get an understanding of the importance of this function‚ one needs to know some history about it. Dating back to the times of Euclid‚ the prime numbers have been studied in great deal

First of all‚ according to Vinod (2008 -2013) books of prime entry are books where transactions are first recorded. These may or may not be part of the double system. These are not accounts; they are simply books that record details of transactions. Books of prime entry are also known as books of original entry / subsidiary book/ daybooks among others. In any organization where company’s buy and sell goods‚ will need to divide the journal into subsidiary books. And they are as follows: Sales
