3. Let T =
(a) Suppose that a E T and b e T, and c is a positive integer. Prove
that if a = bc, then c E T.
(b) Demonstrate that every element of T can be factored as a prod-
uct of irreducible elements of T.
(c) Perform a sieve to find all irreducible elements of T between 1
and 100.
(d) Find three examples of elements of T with nonunique factoriza-
tions into irreducibles.
