20 is a term because 25 is the least solution of 20 = A000010(x) and gcd(20,25) equals the number of solutions 5.
7812 is a term because 9121 is the least solution of 7812 = A000010(x) and gcd(7813,9121) equals the number of solutions 7.
1764 is not a term because 2107 is the least solution of 1764 = A000010(x) and gcd(1764,2107) = 49 does not equal the number of solutions 7.
