The numbers that go into 17 are 1 and 17, as 17 is a Prime number and only divisible by 1 and itself. The numbers that go into 20 are 1, 2, 4, 5, 10, and 20, as 20 is a composite number with multiple factors.
17/20 is the simplest form. While 20 is a composite number, 17 is prime. Thus no numbers other than 17 (and 1) could be factored out and 17 does not go into 20.

Assume that the question requires two numbers to be found. Label the numbers a and b. Then ab = 20, so b = 20/a. And, a + b = 17 .............substituting for b gives :- a + 20/a = 17..................multiplying throughout by a, a2 + 20 = 17a. Which we can re-write as, a2 - 17a + 20 = 0. Using the quadratic formula leads to, a = [17 ± √209] / 2 Thus, a = 15.7284 and 1.2716. So the answer is that one number is 15.7284 and the other number is 1.2716. (4dp)

17/20 is the simplest form. While 20 is a composite number, 17 is prime. Thus no numbers other than 17 (and 1) could be factored out and 17 does not go into 20.
The prime numbers between 15 and 20 are 17 and 19. To find the product of these two prime numbers, you simply multiply them together: 17 x 19 = 323. Therefore, the product of the prime numbers between 15 and 20 is 323.
20
The prime numbers between 10 and 20 are 11, 13, 17, and 19.
1,2,3,4,5,6,10,12,15,20,30,60
The prime numbers between 10 and 20 are 11, 13, 17, and 19.
11, 13, 17, and 19
17 and 37 17 x 37 = 629 37 - 17 = 20.
The numbers that add to -17 and multiply to 20 are -5 and -4. When you add -5 and -4, you get -17. When you multiply -5 and -4, you get 20.
3 + 17 = 20
They are 3+17 = 20
6 numbers can go into 20; they are 1, 2, 4, 5, 10 and 20.
