Prove that √2 is an irrational number.
If the HCF of two positive integers a and b is 1, then their LCM is :
Assertion (A) : For any two natural numbers a and b, the HCF of a and b is a factor of the LCM of a and b. Reason (R) : HCF of any two natural numbers divides both the numbers.
The value of (HCF – LCM) for the two numbers 3 and 5 is :
