Discussion

Explanation:

The required number should be of the form A × x (where x is any positive integer)

Also, B should be divisible by A × x

Now, 20202022 = 20202020 × 20202

Number of possible values of x will be same as the number of factors of 20202.

20202 = 24 × 52 × 1012

Number of factors of 20202 = (4 + 1) × (2 + 1) × (2 + 1) = 45.

Hence, option (c).
