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
It is: 14
126 = 14 x 9
196 = 14 x 14
378 = 14 x 27
ans:14
and u call that

a smartass
It is: 4
The GCF is 28.
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
i dont know
The GCF is 14.
The highest common factor is 2
4
It is: 4
The Greatest Common Factor (GCF) is: 28
The GCF is 28.
The HCF is 28.
The GCF is 28.
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
The greatest common factor of 196 and 420 is 28.
The greatest common factor of 42 and 196 is 14.
