In mathematics

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