Prove that √2 is an irrational number.
If the HCF of two positive integers a and b is 1, then their LCM is :
The value of (HCF – LCM) for the two numbers 3 and 5 is :
Using prime factorisation, find the HCF of 180, 140 and 210.
The HCF of 95 and 152, is
Assertion: For any two positive integers a and b, HCF(a, b) × LCM(a, b) = a × b Reason: The HCF of two numbers is 5 and their product is 150. Then their LCM is 40.
