I'm guessing you mean HCF. You need to find the different factors of each number and then find the biggest one that is common in all 3:126= 1 & 126, 196=1 & 196, 378=1 & 378,

2 & 63, 2 & 98, 2 & 189,

3 & 42, 4 & 49, 3 &126,

6 & 21, 7 & 28, 6 & 63,

7 & 18, 14 &14 7 & 54,

9 & 14 9 & 42,

14 & 27,

18 & 21

I believe that the highest common factor would be 14
