Multiply common terms in the two number to get HCF
1) 12 and 24
12 = 2 × 2 × 3
24 = 2 × 2 × 2 × 3
HCF of 12 and 24 is 2 × 2 × 3 = 12

2) 81 and 162
81 = 3 × 3 × 3 × 3
162 = 2 × 3 × 3 × 3 × 3
HCF of 81 and 162 is 3 × 3 × 3 × 3 = 81

3) 13 and 19
13 = 13 × 1
19 = 19 × 1
HCF 13 and 19 is = 1

1) 36 and 24
36 = 2 × 2 × 3 × 3
24 = 2 × 2 × 2 × 3
HCF 36 and 24 is 2 × 2 × 3 = 12
