So the Greatest Common Divisior 26, 91, 68, 74 is 1.

Therefore, GCD of numbers 26, 91, 68, 74 is 1

Given Input Data is 26, 91, 68, 74

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

Prime Factorization of 26 is 2 x 13

Prime Factorization of 91 is 7 x 13

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 74 is 2 x 37

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(26, 91) = 182

GCD(26, 91) = ( 26 x 91 ) / 182

GCD(26, 91) = 2366 / 182

GCD(26, 91) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 68

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

LCM(13, 68) = 884

GCD(13, 68) = ( 13 x 68 ) / 884

GCD(13, 68) = 884 / 884

GCD(13, 68) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 74

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

LCM(1, 74) = 74

GCD(1, 74) = ( 1 x 74 ) / 74

GCD(1, 74) = 74 / 74

GCD(1, 74) = 1

GCD of 26, 91, 68, 74 is 1
