Use Dirichlet’s Theorem on
Primes in Arithmetic Progressions
Homework Answers
Now we will use Dirichlet's Theorem on Primes in Arithmetic Progression, which says
Suppose that a and b are relatively prime positive integers, then the arithmetic progression an+b, for all natural numbers n, contains infinitely many primes.
Therefore, the arithmetic progression
8m+5, for all natural number m
With 8 and 5 being relatively prime, contains infinitely many primes.
Hence the desired result follows.

Suppose that pı, P2, ..., P, are the only primes congruent to 1 (mod 4). Prove that 4p?p, ... p, + 1 is divisible only by primes congruent to 3 (mod 4). Assuming that all odd prime factors of integers of the form x2 +1 are congruent to 1 (mod 4), use Exercise 6 to prove that there exist infinitely many primes congruent to 1 (mod 4).

Use python for programming the fundamental theorem of arithmetic (single factorization theorem), which affirms that every positive integer greater than 1 is a prime number or a single product of prime numbers. Show the factors in a list and show a dictionary where the keys are the factors of the number entered and the values are how many times each factor appears in the unique combination.

Prove that there exists infinitely many numbers of the form an = n(n+1)/2 , for some positive integer n, such that every pair an, am (for n != m) are relatively prime. [Hint: Assume there exists a finite sequence an1 < an2 < an3 < . . . < anm, where nj are increasing positive integers. Show that using those numbers we can construct a new number that fulfills the requirements.]
