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 :
State the "Fundamental Theorem of Arithmetic" and use it to find LCM of 36 and 54.
If p = 2³ × 3² × 5 and q = 2² × 3³, then the LCM of p and q is :
