Primes & Prime Factorization
Every positive integer greater than 1 decomposes uniquely into prime building blocks.
What you'll learn
- Distinguish prime, composite, and the special number 1 by counting positive divisors.
- Build a complete prime factorization by splitting every composite factor.
- Explain why different factor-tree paths produce the same prime multiset.
- Use exponents to record repeated prime factors and reconstruct the original number.
