In this paper, we study some divisibility properties of palindromic numbers in a fixed base g ≥. 2. In particular, if P L denotes the set of palindromes with precisely L digits, we show that for any sufficiently large value of L there exists a palindrome n ∈ P L with at least (log log n) 1+o(1) distinct prime divisors, and there exists a palindrome n ∈ P L with a prime factor of size at least (log n) 2+o(1).
