What is the greatest common factor (gcf) for 26 and 78? 61326 32

For this case we have that by definition, the GCF of two numbers is the biggest common factor that divides both numbers without leaving residue. We find the factors:

26: 1,2,13,26

78: 1,2,3,6,13,26

Thus, the GCF of both numbers is 26

26

Option C

1/800 is the right answer

i think that you should ask google for the answer to that problem because if we don't know it google does
