Which of the following is the statement of Fundamental Theorem of Arithmetic?
Given positive integers a and b, there exist unique integers q and r satisfying a = bq + r, 0 ≤ r < b.
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.
For any two positive integers a and b, HCF (a,b) × LCM (a,b) = a × b.
HCF (p, q, r) × LCM (p, q, r) ≠ p × q × r, where p, q, r are positive integers.
