FAQ
What methods can students use to find the prime factorization of a number?⌄
The two most common methods are repeated division (dividing by the smallest prime that works, continuing until the result is 1) and factor trees (branching a number into any two factors until all branches end at primes).
Why is the prime factorization of a number considered its 'fingerprint'?⌄
By the Fundamental Theorem of Arithmetic, every whole number greater than 1 has exactly one prime factorization (ignoring order) — this uniqueness makes prime factorization a powerful tool for comparing and analyzing numbers.
How does prime factorization of numbers up to 200 help with fraction work?⌄
When simplifying fractions, students can compare the prime factorizations of numerator and denominator to quickly find all common factors and cancel them, rather than guessing which numbers divide both.
