Which of the following must divide into n means which of the following must be factor of n

68 is NOT essentially a factor of 34

If 2 and 17 are factors of positive integer n, then which of the following must also divide into n?

I. 34
II. 68
III. 136

A. I only
B. II only
C. I and II only
D. I and III only
E. None


Since the LCM of 2 and 17 is 34, we see that, of the answer choices, only 34 must divide into n.

Answer: A

\(n = 2^x*17^y*............... \)(Any other number in the blank space and x and y can take any value)

So, n must also divide into 34, Answer must be (A) ,I
