Question

Find the common factors of the terms

(i) 12x, 36

(ii) 2y, 22xy

(iii) 14pq, 28p²q²

Answer 1

(i) 12x = 2 × 2 × 3 × x

36 = 2 × 2 × 3 × 3

(ii) 2y = 2 × y

22xy = 2 × 11 × x × y

(iii) 14pq = 2 × 7 × p × q

28p²q² = 2 × 2 × 7 × p × p × q × q

The common factors are 2, 7, p, q.

And, 2 × 7 × p × q = 14pq
