Study Notes
Properties of HCF and LCM
- The product of HCF and LCM of two numbers is always equal to the product of the numbers.
- HCF(a, b) × LCM(a, b) = ab, where a and b are two numbers.
HCF of Numbers
- The HCF of 26 and 191 is 1.
- The HCF of 39 and 91 is 13.
Properties of Integers
- The product of two consecutive integers is always divisible by 2.
Types of Numbers
- A number of the form p/q, where q ≠ 0, is a rational number.
- A rational number is not a whole number.
- The product of two different irrational numbers is not always rational.
- The sum of a rational and an irrational number (excluding zero) is an irrational number.
Properties of Coprime Numbers
- The HCF of two coprime numbers is always 1.
