3 Concept Maps

Prime Factorization Process - Step by Step Decision Tree

Prime Factorization Process - Step by Step Decision Tree

The map in words

  • Start: Find Prime Factorization
    • Is the number divisible by 2?
      • Yes: Divide by 2, write down 2
        • Repeat with result
          • Is result = 1?
            • No: Is number divisible by current prime?
              • Yes: Divide and write down prime
                • Repeat process
              • No: Move to next prime
            • Yes: Factorization Complete
              • Write as product: 2^a × 3^b × 5^c ...
                • Verification: Multiply factors
                  • Product = Original?
                    • Yes: Correct!
                    • No: Check your work
      • No: Try next prime: 3, 5, 7, ...
