Pandigital | 7*p, 8*q, 9*r; p,q,r are prime numbers

 
 

413 \; = \; 7 \; \times \; 59 ………. = \; 7 \, p_1
568 \; = \; 8 \; \times \; 71 ………. = \; 8 \, p_2
927 \; = \; 9 \; \times \; 103 ……… = \; 9 \, p_3

 

The combined digits of the numbers   7 \, p_1, \; 8 \, p_2, \; 9 \, p_3   use all nine digits 1 – 9 exactly once each

413 \; || \; 568 \; || \; 927 \; = \; 413568927

and the product of   7 \, p_1, \; 8 \, p_2, \; 9 \, p_3

413 \; \times \; 568 \; \times \; 927 \; = \; 217459368

is a 9-digit number containing each digit 1 – 9.
