if average of 9 consecutive positive integers is 63 then its middle number is 63, so number series becomes
(63-4), (63-3), (63-2), (63-1), 63, (63+1), (63+2), (63+3), (63+4)

59, 60, 61, 62, 63, 64, 65, 66, 67

Fifth number = 63

Smallest number = 59

Largest number = 67

Required product = 59 × 67 = 3953
