Answer 2

Answer:

1) 20 and 25

20 = 2 * 2 * 5

25 = 5 * 5

HCF = 5

(Since both of them has 5 with degree 1)

2)70 and 105

70 = 7 * 2 * 5

105 = 5 * 3 * 7

HCF = 5 * 7 = 35

(since both of them has 5 with degree 1 and 7 with degree 1)

3)55 and 33

55 = 5 * 11

33 = 3 * 11

HCF = 11

(Since both of them has 11 with degree 1)
