Question

Fill out the HCF of the following pairs.
HCF (8,12)=

HCF (18,27)=

HCF (16,24)=

Answer 1

Answer:

HCF OF 8 AND 12 =

Factors of 8 = 1 , 2 , 4 , 8

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

So the highest common factor is 4

HCF OF 18 AND 27 =

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

Factors of 27 = 1 , 3 , 9 , 27

So the highest common factor is 9

HCF OF 16 AND 24 =

Factors of 16 = 1 , 2 , 4 , 8 , 16

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

So the highest common factor is 8

Answer 2

HCF of 18, 27 is 9

HCF of 16, 24 is 8

HCF of 8, 12 is 4
