What Makes a Number a Smith?
Imagine playing with building blocks. You can take a big number and break it down into smaller pieces, its prime factors. A Smith Number has a fascinating property: the sum of its digits is the same as the sum of the digits of its prime factors.
Let's take the number 27 for a spin.
- Breaking it down: The prime factors of 27 are 3 x 3 x 3.
- Adding the digits: 2 + 7 = 9
- Adding the prime factor digits: 3 + 3 + 3 = 9
Voila! Both sums are 9, making 27 a certified Smith Number.
The Phone Book Connection: A Mathematical Discovery
You might be surprised to learn that Smith Numbers weren't discovered in a dusty math book, but in a phone book! Mathematician Albert Wilansky noticed something peculiar about his brother-in-law, Harold Smith's, phone number: 493-7775. It turned out to be a Smith Number, and thus, a new mathematical concept was born!
The Notorious 666: A Smith Number with a Reputation
Even the infamous 'number of the beast,' 666, has a hidden Smith Number identity!
