What are Real Numbers?
Real numbers can be defined as the combination of all the rational numbers and all the irrational numbers. Any number be it positive, negative, decimals, fraction, or natural are real numbers which is denoted by the letter “R”.
Euclid’s Division Lemma
Euclid’s Division Lemma is defined as “for a given positive integer a and b, there exist unique integers q and r satisfying \([a = bq+ r, 0 \leq r < b]\). An example is given below which will explain this concept better.
The Fundamental Theorem of Arithmetic
This theorem states that “every composite number can be expressed (factorized) as a product of primes, and this factorization is unique, apart from the order in which the prime factors occur.”
An example includes 36 which can be written as 22×32
