63

63 is a Harshad number because it is "is an integer that is divisible by the sum of its digits when written in that base". What I mean is that 6+3=9 and 63 divides into 9 without leaving a remainder (63/9=7).

67

67 is a prime number which means you cannot divide it by any whole number other than 1 or itself, without leaving a remainder. It is the sum of five consecutive prime numbers 7 + 11 + 13 + 17 + 19 = 67.

Sorry about this, I am feeling really mathematical this morning. Numbers are kinda an obsession with me :wacko: .
