VTU 4th Sem Math | Counting Numbers Divisible by 5, 6, or 8 | Principles of Counting II - Module 4

n this video, I solve an important problem from Principles of Counting II, Module 4 of the 4th Semester VTU Mathematics syllabus. The question is: How many integers between 1 and 300 (inclusive) are: (i) Divisible by at least one of 5, 6, or 8? (ii) Divisible by none of 5, 6, or 8? This problem is explained step by step using the principle of inclusion-exclusion, making it easy for VTU students to understand how to efficiently count numbers with multiple divisibility conditions.
