Let us find the effective number of Cu, Ag and Au atoms in a unit cell,
1) The effective number of Cu atoms in a unit cell =
 equals 8 cross times 1 over 8 plus 6 cross times 1 half

equals space 1 space plus space 3 space

equals space 4

2) The effective number of Ag atoms in a unit cell = 
equals space 12 space cross times 1 fourth
equals space 3

3) The effective number of Au atoms in a unit cell = 1
So, the general formula of the alloy is Cu4Ag3Au
