Grow a tree to reveal prime factorization!
Every composite number can be expressed as a unique product of prime numbers. This is called the Fundamental Theorem of Arithmetic.
Algorithm: Keep dividing by the smallest prime factor until you reach 1.
Example: 60 = 2 × 30 = 2 × 2 × 15 = 2 × 2 × 3 × 5 = 2² × 3 × 5
