Number
$192$ (one hundred and ninety-two) is:


 * $2^6 \times 3$


 * The $31$st happy number after $1, 7, 10, 13, 19, 23, \ldots, 91, 94, 97, 100, 103, 109, 129, 130, 133, 139, 167, 176, 188, 190$:
 * $192 \to 1^2 + 9^2 + 2^2 = 1 + 81 + 4 = 86 \to 8^2 + 6^2 = 64 + 36 = 100 \to 1^2 + 0^2 + 0^2 = 1$


 * The $2$nd positive integer after $128$ with $7$ or more prime factors:
 * $192 = 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 3$


 * The $6$th positive integer after $64, 96, 128, 144, 160$ with $6$ or more prime factors:
 * $192 = 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 3$


 * The $2$nd element of the $1$st set of $3$ integers $T$ such that $m \tau \left({m}\right)$ is equal for each $m \in T$:
 * $168 \times \tau \left({168}\right) = 192 \times \tau \left({192}\right) = 224 \times \tau \left({224}\right) = 2688$


 * The $1$st of $4$ integers $n$ such that $n + 2 n$ can be expressed as a sum using each of the digits $1$ to $9$ exactly once each:
 * $192 + 384 = 576$


 * The $38$th positive integer $n$ such that no factorial of an integer can end with $n$ zeroes.
