Factors of 52 are = 52 , 26, 13 , 4 , 2 and 1
so there are \(6\) possible values for x

If we want to make x an integer x has to be the factors of 52.
So,
52 = 26*2 = 13 * \(2^2\)
there is a shortcut to find out the total factor. Just add 1 to the power of the prime.
so, (1+1)*( 2+1) = 6
The best answer is B.
