Question

2 prime numbers when multiplied get 80

Answer 1

The formula to solve this would be:
X×Y=80

There are at least two combinations of two numbers that you can multiply together to get 80.

For your convenience, I've made a list of all the combinations of two numbers multiplied by each other that will make 80:

$1 \times 80 = 80 \\ 2 \times 40 = 80 \\ 4 \times 20 = 80 \\ 5 \times 16 = 80 \\ 8 \times 10 = 80 \\ 10 \times 8 = 80 \\ 16 \times 5 = 80 \\ 40 \times2 = 80 \\ 80 \times 1 = 80$
