Suppose (n) admits two factorizations [ n = p_1p_2\dots p_r=q_1q_2\dots q_s, ] where each (p_i) and (q_j) is prime. By Euclid’s lemma, (p_1) divides the product on the right, so (p_1=q_j) for some (j). Canceling this common prime from both sides and repeating the argument yields (r=s) and the two lists of primes are the same up to order. ∎

Some modern readers find the book a "wonderful text," while others consider it slightly "outdated". This "dated" quality is often about its physical format and specific exam board alignment, not the correctness of its mathematics. For building a timeless, rigorous foundation in pure mathematics, J. K. Backhouse's work remains an exceptional resource.
A rigorous introduction to limits, first principles, optimization problems, areas under curves, and standard integration techniques.
Pearson has a modern ebook version under a different ISBN (978-0582353875). It is not free, but it is legal, searchable, and contains the full content. You can rent it for 180 days for approximately $30-40.
