Q1. Compute the GCD using the improved version of Euclid's Algorithm (e.g., 375 & 825, and 81000 & 51000). Q2. Assume m is greater than n. Verify that d divides m and n if and only if d divides both n and m mod n. Q3. Write an algorithm to check if n is a prime number. Q4. Write an algorithm to compute the list of divisors of n that are prime numbers. Q5. Write an algorithm to compute the prime factorization of a number and use it to find the GCD of two numbers. 📚 This lecture is useful for Class 9 students of CBSE, ICSE, UP Board, Bihar Board, MP Board, Haryana Board, Punjab Board, and all other state boards following the Ganita Manjari / NCERT syllabus for Session 2026-27. 👨‍🏫 ABOUT THE TEACHER: Sanyam Bhayana is a Class 12 State Topper (99.8%) and Gold Medalist from Shri Ram College of Commerce (SRCC), New Delhi.
