Try 2 times 16 = 32 as one example
1 x 196 = 196
because prime numbers have to be multiplyed by 1 and itself for example 17 it can only be multiplyed by 1 and itself.
The numbers are: 32+29 = 61
5, 7 and 11
32 and any factor of 32.
17 x 17
(242,2)(121,4)(44,11)
1 x 289 = 289
1 x 196 = 196
1 multiplyed by 1 is 1!
15
because prime numbers have to be multiplyed by 1 and itself for example 17 it can only be multiplyed by 1 and itself.
The numbers are: 32+29 = 61
In this case, two numbers are possible. The numbers which satisfy the above criteria are 32 and -32.
16 and 32
32 and 64
16 and 32
