Break positive integers into prime products such as 360 = 2³ × 3² × 5.
Every integer greater than 1 factors uniquely into primes (fundamental theorem of arithmetic). Prime factorization powers GCF and LCM via highest and lowest exponents per prime.
Trial division by primes 2,3,5,7,... is efficient for classroom sizes. Larger numbers use optimized algorithms, but the result structure is the same: primes with exponents.
Factor trees visualize splitting composites until all leaves are prime. The product of leaf primes equals the original number regardless of split order.
Use factorization to simplify radicals √(72) = 6√2, solve divisibility puzzles, and understand why 1 is not prime (it would break unique factorization).
Provide n > 1.
Start with 2, then 3, 5, ...
Count repeats for each prime.
