Apologies if this is a 2x post, but I did try to search for this question first.
If N is a positive integer, is the units digit of N equal to zero?
(1) 14 and 35 are factors of N
(2) N = (2^5)(3^2)(5^7)(7^6)
The official answer is D (Each alone is sufficient).
I tried to work this out, and I just want some clarification from anyone as to whether it is possible for the two statements above to give you different answers?
thanks
