Title: Review Exercise | Factors and Multiples | Unit 2 | Mathematics Class 4 | Part 6 Subtitle: Complete Revision of Divisibility Rules, Prime Numbers, Factors, Multiples & More Topics Covered: Divisibility Rules for 2, 3, 5, and 10 Prime and Composite Numbers Identification Prime Factorization of Given Numbers Finding Factors of Given Numbers Finding First Six Multiples of Given Numbers Common Factors of Two or More Numbers First Common Multiple of Given Numbers Video Summary: In this video, we solve the Review Exercise of Unit 2 (Factors and Multiples), providing a comprehensive revision of all key concepts covered in the unit. We begin with multiple choice questions covering prime numbers, divisibility rules, prime factorization, common factors, and common multiples. Next, we practice applying divisibility rules for 2, 3, 5, and 10 to determine which numbers are divisible by each. We identify the first 12 composite numbers (4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21) and the prime numbers between 21 and 60 (23, 29, 31, 37, 41, 43, 47, 53, 59). We practice finding factors of ten numbers (10, 25, 35, 46, 23, 16, 4, 47, 38, 20) and finding the first six multiples of four numbers (2, 6, 5, 9). Prime factorization is applied to ten numbers (5, 19, 22, 15, 40, 21, 8, 30, 41, 38), breaking each down into its prime factors. We find common factors for pairs and triples of numbers (4 and 20, 16 and 24, 28 and 56 and 14, 17 and 34, 12 and 6 and 18, 5 and 10 and 20). Finally, we find the first common multiple for given numbers (2 and 7, 6 and 10, 12 and 14 and 18, 15 and 30, 5 and 15 and 20, 6 and 12 and 15). The lesson concludes with a complete review of the unit, reinforcing all concepts learned in Unit 2.
