Qty A is 4*x

Prime factor of 4 is 2.
Hence qty A is unique prime factors of x + 1(to account for 2 as a factor of 4)
However x is a even number which means x is definately a multiple of 2. Therefore we do not have to add extra 1
From this it follows that unique prime factors of 4x is same as the unique prime factors of x.
