The only answers are 1 and 2.
Meaning 1 and 2 are the only numbers that you can divide 170 and 12 by and get whole numbers (no decimals) as answers.
170 / 1 = 170
12 / 1 = 12
170 / 2 = 85
12 / 2 = 6
Try it with any other number and you'll see that at least one of your answers will not be a whole number.

Any real number can go into 170. You probably have some limiting factors you want to describe in the question.
The number that goes into 153, 170, and 187 is 17. This is because 153 ÷ 17 = 9, 170 ÷ 17 = 10, and 187 ÷ 17 = 11, resulting in whole number quotients for each division. Therefore, 17 is the common factor that divides evenly into all three numbers.
