Answer 2

Given :  2/4 , 10/8 , 4/12 , 6/15  

To find : HCF  

Solution:

To find  HCF  of  

2/4 , 10/8 , 4/12 , 6/15  

Lets first Simplify Each  number

1/2   ,  5/4   ,   1/3  ,   2/5

now to Convet each number with same denominator

find LCM of Denominators

2  , 4  , 3 & 5

= 60

So we can write each term

30/60   ,  75/60   ,   20/60   ,  24/60

Now we will find HCF  of  30 , 75 , 20 &  24

30 = 2 * 3 * 5

75 = 3 * 5 * 5

20 = 2 * 2 * 5

24 = 2 * 2 * 2 * 3

No common Factor in all

Hence HCF = 1

So HCF of 2/4 , 10/8 , 4/12 , 6/15  =  1/60
