P= 3 to the power of 7*11 to the power of 2 and Q=3 to the power of 4*7 to the power of 3*11.
Write as the product of prime factors.
The LCM of P and Q and the HCF of P and Q.
LCM= 3 to the power of 7*7 to the power of 3*11 to the power of 2.
HCF=3 to the power of 4*11
Am I just retarded or does it make no sense on how you get to that answer especially when you have under 2 minutes to do the question.
