Listener crossword 4010: Euclid's Algorithm by Aedites
NAME

PHONE NUMBER
The first correct entry drawn will receive a copy of Chambers Crossword Dictionary; two runners-up will receive a copy of an anthology of puzzles from the Chambers range. Write your name and contact details in the space provided and send to: Listener Crossword No 4010, 63 Green Lane, St Albans, Hertfordshire AL3 6HE, to arrive by December 11.
All entries are distinct five-digit integers whose factors are restricted to the first 22 prime numbers, 2 to 79, such that there are no repeated factors in any entry. No entry starts with a zero. Circular entries (labelled A to Z) are read clockwise, and radial entries (labelled 1 to 40) are read from the rim to the centre. When a circular entry intersects a radial entry, the clue gives their highest common factor as a product of primes, which are represented by different letters of the alphabet. If the two entries are co-prime (that is they have no factor in common), the clue is omitted.
