Question

State whether 45 ? 34 ? 23 ? 17 is composite or prime number.

Answer 1

Hi,
​Question must be: whether 45 x 34 x 23 +17 is composite or prime number.
=45 x 34 x 23 +17

=45 x 2 x17 x 23 +17

=17[45 x17 x 23 +1]
so here it has more than two factors, 1,17 and number itself so it is composite
