A question from session 3

A degree of 1 in which of the following below would result in the greater decrease in the product?

A 11

B 13

C 17

D 19

E 23

im confused to why its not 23
P= (the prime factors listed) X i^x-1, if we rewrite using exponents rule its P=P/i and if we were to divide by 23 that would make the product decrease the most?

Share the screenshot of the question - this isn’t clear enough.

i added the screen shot : )

OK the question is https://gmatclub.com/forum/a-decrease-of-1-in-which-of-the-factors-above-would-result-in-the-grea-327323.html (there was something “above”).

\frac{x}{10} > \frac{x}{23}
