I didn't see the program, but I did see something TheSun website before his explanation was goind to be aired and after.
Before, their suggestion how it might of been done:-

Noting
Paul Daniels comments further down the page!
After, with remarks (in the story) from two Maths Experts:-

Obviously and as per Paul Daniels comments he used "gobbledegook" in his explanation. The big giveaway with the explanation ( if the maths wasn't enough) is that he's mixed mathematics with "ancient" stories. He's sort of made a whole follow-up show comprise of some tongue-in-cheek "trickery", but then he is an entertainer.
