The given number : 2021
Factors of 2021 are :
[tex]2021=43\times47[/tex]So, the proper factors of 2021 are 43 and 47
The smallest difference between any two proper factors of 2021 : Difference between 47 and 43
Diffrence between 47 and 43 = 47 - 43
Diffrence between 47 and 43 = 4
The smallest difference between any two proper factors of 2021 =Difference between 47 and 43 = 4
Answer : The smallest difference between any two proper factors of 2021 is 4
