In mathematics

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 (142).
  • 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.
  • an odious number.
  • a powerful number.
  • a practical number.
  • an 11-gonal number.
  • a 34-gonal number.
  • a pentagonal pyramidal number.
  • a heptagonal pyramidal number.
  • palindromic in bases 13 (12113), 27 (7727), 48 (4448), 97 (2297) and 195 (11195).
  • 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.

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

    Possible Lychrel number

    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.
