Sorry should have named the crossword - listener 4114. Can I check if anyone agrees with 693 for E3? I seem to have come to a halt further on so would like to check on one clue.

I don't think that 693 works because the resulting triangle would be (693, 324, 765), which fails the coprimality test (since each of the three numbers is divisible by 3).

Thanks for reply. Found it was 777 and completed the grid but can't thank of theme to finish shaded squares.
