Suppose a is a positive integer and p is a prime/ Prove that p|a
if and only if the prime factorization of a contains p.
Can someone please show a full proof to this, thank you.
Let p be an integer other than 0, ±1.
(a) Prove that p is prime if and only if it has the property
that whenever r and s are integers such that p = rs, then either r
= ±1 or s = ±1.
(b) Prove that p is prime if and only if it has the property
that whenever b and c are integers such that p | bc, then either p
| b or p | c.
Use the Well-Ordering Principle of the natural numbers to
prove that every positive
rational number x can be expressed as a fraction x = a/b where
a and b are postive
integers with no common factor.

Write a python function that receives two positive numbers and
displays the prime numbers between them.Note: A prime number (or a
prime) is a natural number greater than 1 and that has no positive
divisors other than 1 and itself.
