Question

We write all the factors of 24 and 36.
Factors of 24 = 1, 2, 3, 4, 6, 8, 12, 24
Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36
Common factors of 24 and 36 are 1, 2, 3, 4, 6, 12.
Largest among the common factors is 12 i.e., H.C.F. =

Answer 1

Answer:

(i)18,48

18=1,2,3,6,9,18

48=1,2,3,4,6,8,12,24,48

6 is HCF

(ii)12,16,28

12=1,2,3,4,6,12

16=1,2,4,8,16

28=1,2,4,7,14,28

4 is HCF

Answer 2

Step-by-step explanation:

We write all the factors of 24 and 36.

Factors of 24 = 1, 2, 3, 4, 6, 8, 12, 24

Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36

Common factors of 24 and 36 are 1, 2, 3, 4, 6, 12.

Largest among the common factors is 12 i.e., H.C.F. =

Prime Factorisation Method To Find H.C.F.

Step 1 : Write the prime factorisation of each of th

Step 2 : Find the common prime factors of the giv

Step 3 : The product of all common factors (of ste
