To find the highest common factor (HCF) of 126, 196, and 378, we first need to find the prime factors of each number. The prime factors of 126 are 2 x 3 x 3 x 7, the prime factors of 196 are 2 x 2 x 7 x 7, and the prime factors of 378 are 2 x 3 x 3 x 3 x 7. To find the HCF, we look for the common prime factors among the numbers, which are 2 and 7. Multiplying these common factors gives us the HCF, which is 14.
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
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.
