## In mathematics

Having only 2 and 3 as its prime divisors, 162 is a 3-smooth number.[1] 162 is also an abundant number, since its sum of divisors ${\displaystyle 1+2+3+6+9+18+27+54+81=201}$ is greater than it.[2] As the product ${\displaystyle 3\times 6\times 9=162}$ of numbers three units apart from each other, it is a triple factorial number.[3]

There are 162 ways of partitioning seven items into subsets of at least two items per subset.[4]
