Question

It is being given that 23 is completely divisible by a whole number. Which of the following numbers is completely divisible by this number? (A) 216+ 1 (C) 7 x 223 (B) 216-1 (D) 296+1​

Answer 1

Correction here is 23==>2³²

The factors of 2³² are

2×2×2×2×2......32 times

We can say that 2 completely divides 2³²

From the options by simplifying them,

A)217

B)215

C)1561

D)297

No option is divisible by 2

Hence the answer is none of the above ,

But if we take 1 as a factor of 2³²

then all the answers are correct
