As an attempt to follow the direction of machine proof, a personal com
puter LEO386/25 is used to prove some class number formulae for certai
n imaginary quadratic number fields Q(root p), (q = 3, 7, 11, 19, 23,
31, 43 and 47) ii the real quadratic number field Q(root-p) has class
number one for a prime p = 4N(2) + 1 (N is a positive integer).
