The Correct Option is B
Solution and Explanation
The correct option is (B): 4.
We will try to find a pattern in the last three digits of the given number.
Last three digits of:
10051 = 005
10052 = 025
10053 = 125
10054 = 625
10055 = 125
10056 = 625
Now, this pattern will repeat.
From the above pattern, we can say that the last three digits of 10051001
will be 125.
Now, 125 = 33
Thus, the number of factors = 3 + 1 = 4.
