Question

Find out the HCF of the following number using prime factorisation method
42,56 48,56 18,45​

Answer 1

Step-by-step explanation:

Number = prime factorisation

42 = 2 X 3 X 7

56 = 2 ³ X 7

48 = 2⁴ X 3

56 = 2 ³ X 7

18 = 2 X 3²

45 = 1 X 3² X 5

common factor in all = 2

7 is the HCF in 42 , 56 .

At final in all the HCF is 2
