Answer:
a= 1,2,4 b= 1,2,3,6 c=1,2,4 d=1,2,5,10 e=1,2,3,4,6,12 H.C.F of all the pairs= 2
Step-by-step explanation:
Factors of:
a. 8=1,2,4,8
12=1,2,3,4,6,12.
common factor=1,2,4
b. 12=1,2,3,4,6,12
18=1,2,3,6,9,18
common factor=1,2,3,6
c. 16=1,2,4,16
24=1,2,3,4,6,8,12,24
common factor=1,2,4
d. 20=1,2,4,5,10,20
30=1,2,3,5,6,10,15,30
common factor=1,2,5,10
e. 24=1,2,3,4,6,8,12,24
36=1,2,3,4,6,9,12,18,36
common factor=1,2,3,4,6,12
HIGHEST COMMON FACTOR (H.C.F)=
The factor common to the whole pairs
which is 1 and 2
therefore 1 multiplied by 2 which is equal to 2
(and in Mathematics means multiplication)
