• LCM is 72

So, Option C is correct

Answer 2

Answer:

c) is the correct answer..

For just revising HCF I did this. Don't mind it, okay.

a) HCF = 12

b) HCF = 4

c) HCF = 24

d) HCF = 12

Step-by-step explanation:

a) 2 | 12 2 | 24

2 | 6 2 | 12

3 | 3 2 | 6

1 3 | 3

1

Factors of 12 = 2 × 2 × 3

Factors of 24 = 2 × 2 × 2 × 3

HCF of 12 and 24 = 2 × 2 × 3 = 12

b) 2 | 20 2 | 12

2 | 10 2 | 6

5 | 5 3 | 3

1 1

Factors of 20 = 2 × 2 × 5

Factors of 12 = 2 × 2 × 3

HCF of 20 and 12 = 2 × 2 = 4

c) 2 | 24 2 | 72

2 | 12 2 | 36

2 | 6 2 | 18

3 | 3 3 | 9

1 3 | 3

1

Factors of 24 = 2 × 2 × 2 × 3

Factors of 72 = 2 × 2 × 2 × 3 × 3

HCF of 24 and 72 = 2 × 2 × 2 × 3 = 24

d) 2 | 24 2 | 12

2 | 12 2 | 6

2 | 6 3 | 3

3 | 3 1

1

Factors of 24 = 2 × 2 × 2 × 3

Factors of 12 = 2 × 2 × 3

HCF of 24 and 12 = 2 × 2 × 3 = 12
