27385 is a product of two 4k+1 primes and so it can be expressed as a sum of two squares in two different ways viz. 72^2 + 149^2 and 76^2 + 147^2.

27385 is a semiprime for which the digital root of both factors is the same, here 5. See Bespoken for Sequences entry.

27385 is a cyclic and Duffinian number.  

27385 is a de Polignac number because none of the positive numbers 27385 - 2^k is a prime.

27385 can be formed into a digit equation as follows:

(2 + 7) / 3 = 8 - 5

27385 stabilises after about 88 generations of Conway's Game of Life rules to a single glider, a single still life block and two still life beehives.
