WebStrong induction is useful when the result for n = k−1 depends on the result ... Base: 2 can be written as the product of a single prime number, 2. Induction: Suppose that every integer between 2 and k can be written as the product of one or more primes. We need to show WebFundamental Theorem of Arithmetic. The fundamental theorem of arithmetic (FTA), also called the unique factorization theorem or the unique-prime-factorization theorem, states …
Using induction to prove all numbers are prime or a …
The proof uses Euclid's lemma (Elements VII, 30): If a prime divides the product of two integers, then it must divide at least one of these integers. Existence It must be shown that every integer greater than 1 is either prime or a product of primes. First, 2 is prime. Then, by strong induction, assume this is true for all … See more In mathematics, the fundamental theorem of arithmetic, also called the unique factorization theorem and prime factorization theorem, states that every integer greater than 1 can be represented uniquely as a … See more The fundamental theorem can be derived from Book VII, propositions 30, 31 and 32, and Book IX, proposition 14 of Euclid's Elements.

Relevant Equations: None. The proof is by strong induction. Suppose is an S-prime. Then for some . Let be an S-composite such that where are all S-primes.
