If X>1, what are X unique factors of x?
1> There are x unique factors of x
2> The sum of x and any prime number larger than x is odd
can you please explian me the reasoning for this question.
1. If the number has x unique factors, so lets plug in numbers .. say for e.g 2, 2 has 2 factors (1 and 2) lets say 3 then 3 also has 2 factors ( 1,3) similarly if we take some more numbers we will see that all numbers greater than 2 has factors which are not equal to the number ( say 4 has only 3 factors ) hence 2 is the only number which satisfies the condition - Sufficient
2. This only implies that X is an even number, it can 2 or 4 or may be 6 etc. - Insufficient
Whats the OA ?
