So the Greatest Common Divisior 57, 3, 92, 81 is 1.

Therefore, GCD of numbers 57, 3, 92, 81 is 1

Given Input Data is 57, 3, 92, 81

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 57 is 3 x 19

Prime Factorization of 3 is 3

Prime Factorization of 92 is 2 x 2 x 23

Prime Factorization of 81 is 3 x 3 x 3 x 3

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(57, 3) = 57

GCD(57, 3) = ( 57 x 3 ) / 57

GCD(57, 3) = 171 / 57

GCD(57, 3) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 92

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(3, 92) = 276

GCD(3, 92) = ( 3 x 92 ) / 276

GCD(3, 92) = 276 / 276

GCD(3, 92) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 81

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

GCD(1, 81) = 81 / 81

GCD(1, 81) = 1

GCD of 57, 3, 92, 81 is 1
