Real Numbers | Class 10 Maths Chapter 1 Introduction | NCERT 2025 Example 1,2,3,4 CLASS 10 maths all video 👇👇👇    • Class 10 new syllabus   In this video you will learn: 1. Real Numbers: The group of rational and irrational numbers is called real numbers. 2. Rational Numbers: The numbers which we can write in the form of p/q are called rational numbers. Where p and q are integers and q ≠ 0. Example: 2, 5, -7, 3/4 etc. 3. Irrational Numbers: The numbers which we cannot write in the form of p/q are called irrational numbers. Example: √2, √3, √5, π etc. 4. Fundamental Theorem of Arithmetic: According to this theorem, every composite number can be expressed as the product of prime numbers. Example: 50 = 2 × 5 × 5 210 = 2 × 3 × 5 × 7 5. HCF (Highest Common Multiple): It is the product of the smallest power of each common prime factor in the numbers. 6. LCM (Least Common Multiple): It is the product of the largest power of each prime factor in a number. 7. Examples: 120 = 2³ × 3 × 5 180 = 2² × 3² × 5 HCF = 2² × 3 = 12 LCM = 2³ × 3² × 5 = 360 8. Relation between HCF and LCM: HCF × LCM = Number 1 × Number 2 (120 × 180 = HCF × LCM) Like, Share and Share this video with all your Class 10 friends! #Class10Maths #RealNumbers #CBSE2025 #HCF #LCM #RationalNumbers #IrrationalNumbers #MathsChapter1 #upboard #mpboard
