Question

Find the HCF of the following number by prime factorisation method. (a). 76,28 (b). 24,16,36 (c). 38,64,82​

Answer 1

Answer:

Step-by-step explanation:

a) 76 = 28 x 2 + 20

   20 = 8 x 2 + 4

   8 = 4 x 2

So, 4 is HCF of a)

Answer 2

Step-by-step explanation:

the HCF of 76,28 is 4

the HCF of 24,16and 36 is 4

the HCF of 38 , 64,and82 is 2

these all answers are from prime factorisation
