Question

Since every subgroup of Z is cyclic, the intersection and the sum of any two subgroups $(a)$\n and $(b)$ of Z must be cyclic groups. (See the preceding exercise.) Find a formula (in terms of \na and $b$) for a generator for each of these subgroups. [Hint: Experiment with some examples\nfor small values of $a$ and $b$ to see if you can discern a general pattern.]
