## Contents

## In mathematics[edit]

**196** is:

- an even number.
- an abundant number, as the sum of its proper divisors (203) is greater than 196.
- a composite number.
- a square number (14
^{2}). - an Erdős–Woods number, as it is possible to find sequences of 196 consecutive integers such that each inner member shares a factor with either the first or the last member.
^{[1]} - an odious number.
- a powerful number.
- a practical number.
^{[2]} - an 11-gonal number.
^{[3]} - a 34-gonal number.
- a pentagonal pyramidal number.
^{[4]} - a heptagonal pyramidal number.
^{[5]} - palindromic in bases 13 (121
_{13}), 27 (77_{27}), 48 (44_{48}), 97 (22_{97}) and 195 (11_{195}). - a Harshad number in bases 4, 7, 8, 13, 14, 15, 22, 25, 27, 28, 29, (and 17 other bases).
- the aliquot sum of 140, 176 and 386.

**196**, 203, 37, 1, 0

There are 196 one-sided heptominoes, the polyominoes made from 7 squares.

### Possible Lychrel number[edit]

A Lychrel number is a natural number which cannot form a palindromic number through the iterative process of repeatedly reversing its digits and adding the resulting numbers. 196 is the lowest number conjectured to be a Lychrel number in base 10; the process has been carried out for over billion iterations without finding a palindrome, but no one has ever proven that it will never produce one.
