1/3 and 2/5 do not have a greatest common factor.
To find a GCF, you must be able to factor the numbers and then look for common factors.
Example:
60 and 240
60 = 2*2*3*5
240 = 2*2*2*2*3*5
Note that 60 and 240 have in common the factors 2*2*3 = 12, so their GCF is 12
Example:
60 and 240
60 = 2*2*3*5
240 = 2*2*2*2*3*5
Note that 60 and 240 have in common the factors 2*2*3 = 12, so their GCF is 12
