Question

Find the remainder when 83^261is divided by 17

Answer 1

Given:

83^261is divided by 17.

To find:

The remainder when 83^261is divided by 17.

Solution:

1) We will solve this by the remainder theorem.

2) We will represent 83 as the nearest multiple of the 17.

• 83 can be written as 85-2

so the remainder is given by:

• $\frac{(85-2)^{261}}{17}$

3) 85 is the multiple of 17 so this will give you the remainder zero so the term will be:

• $\frac{-2^{261}}{17}$

• $\frac{-2^{260}.-2^{1}}{17}$

• $\frac{{(-2^{4})}^{65}.-2^{1}}{17}$

• $\frac{{16}^{65}.-2^{1}}{17}$

now 16 is represented as multiple of 17

• $\frac{{(17-1)}^{65}.-2^{1}}{17}$

• $\frac{{(-1)}^{65}.-2^{1}}{17}$

• $\frac{{-1}.-2}{17}$

• $\frac{2}{17}$

The numerator is less than the denominator so the remainder is the given numerator of the fraction only.

The remainder when 83^261is divided by 17 is 2
