Therefore, GCD of numbers 57, 843, 119, 257 is 1

Given Input Data is 57, 843, 119, 257

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

Prime Factorization of 57 is 3 x 19

Prime Factorization of 843 is 3 x 281

Prime Factorization of 119 is 7 x 17

Prime Factorization of 257 is 257

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, 843) = 16017

GCD(57, 843) = ( 57 x 843 ) / 16017

GCD(57, 843) = 48051 / 16017

GCD(57, 843) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 119

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

LCM(3, 119) = 357

GCD(3, 119) = ( 3 x 119 ) / 357

GCD(3, 119) = 357 / 357

GCD(3, 119) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 257

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

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

GCD(1, 257) = 257 / 257

GCD(1, 257) = 1

GCD of 57, 843, 119, 257 is 1
