69 great number to what it signifies
A composite with distinct prime factors, and therefore a square-free number.

Also a semi-prime or superficial number. That is, just two prime factors. Plus, a number with as many digits as factors (the smallest such is 10).

Bowmann, there is this book called The Kingdom of the Infinite Number. You should pick it up some time. It has all sorts of interesting facts about different numbers.

This is a "Harshad" number. It is a multiple of the sum of its own digits.

Lest anyone think this is an act of genius, I can report that the only thing Bowmann is likely to be a genius at is using Google.

PS The prime factors of 5,238,197 are 47, 59 and 1889.

PPS I'm kind of chuffed that I managed to pick a number with a lowest factor of 47.
