D. $$\frac{n}{35}$$

E. $$\frac{n}{39}$$

Option A) n/15 =15*28*26/15= 28*26.

Option B) n/21 = 3*5 * 4*7 *26 / 21 = 5*4*26

Option C) 3*5*4*7*13*2 /32 . We don't have 32 in the numerator. This is our answer choice.

Option D) n/35 = 3*5*4*7*13*2 / 35. = 3*4*13*2.

Option E) n/39 = 3*5*4*7*13*2 / 39. 5*4*7*2.

C is the best answer. Re: If n = 15*28*26, which of the following is NOT an integer?   [#permalink] 07 Mar 2019, 01:48
