Write an algorithm to find elements in List 1 that are not present in List 2. Q1 (Part 2). Write an algorithm to find elements in List 2 that are not a part of List 1. Q2. Describe an algorithm to compute the Least Common Multiple (LCM) of two numbers by generating multiples from left to right. Q3. Divisors occur in pairs. If we write out divisors in pairs, how many numbers do we have to examine between 1 and n to find all the divisors of n? Q3 (Second Part). If we list the divisors in pairs, will our GCD (Greatest Common Divisor) algorithm still work in the manner we have described? 📚 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 (99.6%) and Gold Medalist from Shri Ram College of Commerce (SRCC), New Delhi.
