It is their lowest common multiple which is 221 13 and 17 are both prime numbers
Most probably quite a few. However the most obvious is 17*13 = 221.
Nothing goes into 13 evenly other than 1 and 13, so that means it is a prime number.
n + 20 - 17 + 13 - n = 20 - 17 + 13 = 3 + 13 = 16
17
Themselves and their multiples because 17 and 13 are both prime numbers.

Most probably quite a few. However the most obvious is 17*13 = 221.
The whole number between 13 and 17 is 15
Nothing goes into 13 evenly other than 1 and 13, so that means it is a prime number.
n + 20 - 17 + 13 - n = 20 - 17 + 13 = 3 + 13 = 16
17
Let's represent the unknown number as "x." The equation can be written as x - 17 = 13. To solve for x, we add 17 to both sides of the equation to isolate x, resulting in x = 13 + 17. Therefore, the number is 30.
1 and 17 (17 is a prime number).
17 is prime and 68 is 17 times 4, so the number that can go into 17 and 68 is 17.
17.
