🚀 Mastering Maths for Competitive Programming – Part 1 | Divisors, GCD & LCM

🚀 Mastering Maths for Competitive Programming – Part 1 | Divisors, GCD & LCM

Math is the backbone of Competitive Programming.

If you want to solve problems faster, optimize brute force, and think like a top coder — you MUST master number theory fundamentals.

In Part 1, we build strong foundations with:

🔢 What are Divisors?
⚡ Efficient Divisor Finding (√N optimization)
🧠 Prime Factorization Basics
➗ GCD (Greatest Common Divisor)
🔁 Euclidean Algorithm (Why it works)
📉 Time Complexity Analysis
➕ LCM and its relation with GCD
💻 Clean C++ Implementations
🔥 CP Tricks & Common Mistakes

🎯 Why This Is Important

These concepts are used in:

✔ Codeforces Div2/Div1 problems
✔ AtCoder Beginner & Regular contests
✔ Number theory based interview questions
✔ Optimization problems
✔ Mathematical reasoning in CP

If you struggle with math-heavy problems — this series will change that.

No memorization.
Pure intuition + efficient implementation.

📌 Prerequisites:

Basic mathematics
Loops & recursion
Understanding of Big-O

🔔 This is Part 1 of the Mastering Maths for CP Series.
