Sunday Times Teaser 2772 – Madam I’m Adam
by Victor Bryant
My friend chose a four digit palindrome [1] and asked me to guess it.
He gave me clues by telling me, in turn, whether it was divisible by the primes in increasing order (2, 3, …).
I was only able to work out his number when he got to 13.
What was it?
[1] In the Sunday Times, ‘a four digit palindome not the same as the teaser’s number.’ However, this wording makes it unsolvable.
