Whats all this about like.

and did you know Fifty-three is the 16th prime number. It is also an Eisenstein prime.

The sum of the first 53 primes is 5830, which is divisible by 53, a property shared by few other numbers.

53 written in hexadecimal is 35, that is, the same characters used in the decimal representation, but reversed. Three multiples of 53 share this property: 371 = 17316, 5141 = 141516, 99481 =1849916.

But 53 can not be expressed as the sum of any integer and its base 10 digits, making 53 a self number. :)

Isn't that blatantly obvious?

something a little different for 58...

A little self indulgence for 59 :P
