(1) 7p
= 7 × p
Hence, factors of 7p are 7 and p.
(2) 6m
= 2 × 3 × m
Hence, factors of 6m are 2, 3 and m.
(3) 9xy
= 3 × 3 × x × y
Hence, factors of 9xy are 3, 3, x and y.
(4) 22ab
= 2 × 11 × a × b
Hence, factors of 22ab are 2, 11, a and b.
(5) p2q
= p × p × q
Hence, factors of p2q are p, p and q.
(6) 10xy2
= 2 × 5 × x × y × y
Hence, factors of 10xy2 are 2, 5, x, y and y.
