Enter Modular Exponentiation

Solve 53 mod 23 using:

Modular exponentiation

Build an algorithm:

n is our exponent = 3

y = 1 and u ≡ 5 mod 23 = 5

See here

n = 3 is odd

Since 3 is odd, calculate (y)(u) mod p

(y)(u) mod p = (1)(5) mod 23

(y)(u) mod p = 5 mod 23

5 mod 23 = 5
Reset y to this value

Determine u2 mod p

u2 mod p = 52 mod 23

u2 mod p = 25 mod 23

25 mod 23 = 2
Reset u to this value

Cut n in half and take the integer

3 ÷ 2 = 1

n = 1 is odd

Since 1 is odd, calculate (y)(u) mod p

(y)(u) mod p = (5)(2) mod 23

(y)(u) mod p = 10 mod 23

10 mod 23 = 10
Reset y to this value

Determine u2 mod p

u2 mod p = 22 mod 23

u2 mod p = 4 mod 23

4 mod 23 = 4
Reset u to this value

Cut n in half and take the integer

1 ÷ 2 = 0

Because n = 0, we stop

We have our answer
