5 Ways to Check if a Number is Prime (From Brute Force to Super Fast) | Part 1

Want to learn how computers determine whether a number is prime?

In this video (Part 1), we explore 5 different algorithms to check if a number is prime, starting from the most basic approach and progressing to increasingly optimized techniques.

You'll learn:
✔ Method 1 - Basic divisibility check
✔ Method 2 - Improved range divisor check
✔ Method 3 - Reducing sample space
✔ Method 4 - Square root optimization
✔ Method 5 - Advanced optimization

By the end of this video, you'll understand not only how each algorithm works, but also why each optimization makes prime checking significantly faster.
