If two positive integers a and b are written as a = p3q2 and b = pq3; p, q are prime numbers, then HCF (a, b) is:
A. pq
B. pq2
C. p3q3
D. p2q2
Answer:B
If two positive integers a and b are written as a = p3q2 and b = pq3; p, q are prime numbers, then HCF (a, b) is:
A. pq B. pq2 C. p3q3 D. p2q2
Explanation: Since a = p × p × p × q × q,
