Important topics occurring in CBSE Class 10 Maths Chapter - Real Numbers

The Fundamental Theorem of Arithmetic:

Every composite number can be expressed (factorised) as a product of primes, and this factorisation

is unique, apart from the order in which the prime factors occur.

Finding LCM and HCF:

For any two positive integers aa and bb,

HCF (a, b) × LCM (a, b) = a × bHCF (a, b) × LCM (a, b) = a × b

Rational and Irrational Numbers:

• If a number can be expressed in the form p/q where p and q are integers and q ≠ 0, then it is called a rational number.
• If a number cannot be expressed in the form p/q where p and q are integers and q ≠ 0, then it is called an irrational number.
• If a number p (a prime number) divides a2, then p divides a.
• The sum or difference between a rational and an irrational number is irrational.
• The product and quotient of a non-zero rational number and irrational number always result in irrational numbers.
• √p is irrational when ‘p’ is a prime.
