We have, 
          10pq ={\color{DarkRed} 2 \times 5} \times p \times q
           20qr = 2\times{\color{DarkRed} 2 \times 5 }\times q \times r
           30rp ={\color{DarkRed} 2}\times 3{\color{DarkRed} \times 5} \times r \times p
Therefore, the common factors between these three is 

 2 \times 5 =10
