Find the common factors of the given term.

10 pq, 20qr, 30rp










Solution

∵                 10pq = 2 × 5 × p × q = (2 × 5) × p × q
                   20qr = 2 × 2 × 5 × q × r = (2 × 5) × 2 × q × r
                  
                   30rp = 2 × 3 × 5 × r × p = (2 × 5) × 3 × r × p

∴  the common factor = 2 × 5 = 10
