288

Number
$288$ (two hundred and eighty-eight) is:


 * $2^5 \times 3^2$


 * The $8$th pentagonal pyramidal number after $1$, $6$, $12$, $40$, $75$, $126$, $196$:
 * $288 = 1 + 5 + 12 + 22 + 35 + 51 + 70 + 92 = \dfrac {8^2 \left({8 + 1}\right)} 2$


 * The $4$th superfactorial after $1, 2, 12$:
 * $288 = 4\$ = 4! \times 3! \times 2! \times 1!$


 * The $28$th powerful number after $1, 4, 8, 9, 16, 25, \ldots, 144, 169, 196, 200, 216, 225, 243, 256$


 * The smaller of the $2$nd pair of consecutive powerful numbers:
 * $288 = 2^5 \times 3^2$, $289 = 17^2$


 * The $30$th highly abundant number after $1, 2, 3, 4, 6, 8, 10, \ldots, 120, 144, 168, 180, 210, 216, 240$:
 * $\sigma \left({288}\right) = 819$


 * The $11$th positive integer after $64, 96, 128, 144, 160, 192, 216, 224, 240, 256$ with $6$ or more prime factors:
 * $288 = 2 \times 2 \times 2 \times 2 \times 2 \times 3 \left({\times \, 3}\right)$


 * The $4$th positive integer after $128, 192, 256$ with $7$ or more prime factors:
 * $288 = 2 \times 2 \times 2 \times 2 \times 2 \times 3 \times 3$


 * The $20$th untouchable number after $2$, $5$, $52$, $88$, $96$, $120$, $124$, $146$, $162$, $188$, $206$, $210$, $216$, $238$, $246$, $248$, $262$, $268$, $276$
