The GCF is 14.

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

It is: 14 126 = 14 x 9 196 = 14 x 14 378 = 14 x 27

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

The GCF is 126.

126

It is: 44

The GCF is 6.

The GCF is 18.

63

LCM is 126, which is the multiple of the highest power of prime factors in the given numbers (2 x 33 x 7).
