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

To find the highest common factor (HCF) of 196 and 252, we first need to find the factors of each number. The factors of 196 are 1, 2, 4, 7, 14, 28, 49, 98, and 196. The factors of 252 are 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, and 252. The highest common factor of 196 and 252 is 28, as it is the greatest number that divides both 196 and 252 without leaving a remainder.

The GCF is 28.

gcf(126, 196, 378) = 14. Using prime factorization: 126 = 2 x 3² x 7 196 = 2² x 7² 378 = 2 x 3³ x 7 hcf = 2 x 7 = 14
