What numbers multiply to 70?

Answer 1

There are infinitely many possible answers:

1*70, 2*35, 3*(70/3), 4*17.5, 5*14, etc

You can also include irrationals: sqrt(2)*sqrt(2450), etc

And there is no reason to be restricted to two numbers: so 1*2*35, 1*2*3*(70/6) etc

Answer 2

As a product of its prime factors: 2*5*7 = 70
