Question

8.For any two positive integers a and b which is correct: HCF (a,b)×LCM(a,b)=a×b HCF (a,b)×LCM(a,b)=a×b. HCF (a,b)×LCM(a,b)=ab HCF (a,b)×LCM(a,b)=ab. HCF(a,b)LCM(a,b)=a×b.
None of these​

Answer 1

Step-by-step explanation:

$the \: last \: option \: is \: correct \\ hcf(a .\: b).lcm(a.b) = a \times b$

option last
