We found the divisors of 57, 38, 71, 26 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 57, 38, 71, 26 is 1.

Therefore, GCD of numbers 57, 38, 71, 26 is 1

Given Input Data is 57, 38, 71, 26

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

Prime Factorization of 57 is 3 x 19

Prime Factorization of 38 is 2 x 19

Prime Factorization of 71 is 71

Prime Factorization of 26 is 2 x 13

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, 38) = 114

GCD(57, 38) = ( 57 x 38 ) / 114

GCD(57, 38) = 2166 / 114

GCD(57, 38) = 19

Step2:

Here we consider the GCD from the above i.e. 19 as first number and the next as 71

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

LCM(19, 71) = 1349

GCD(19, 71) = ( 19 x 71 ) / 1349

GCD(19, 71) = 1349 / 1349

GCD(19, 71) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 26

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

LCM(1, 26) = 26

GCD(1, 26) = ( 1 x 26 ) / 26

GCD(1, 26) = 26 / 26

GCD(1, 26) = 1

GCD of 57, 38, 71, 26 is 1
