We found the divisors of 34, 17, 11, 77 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 34, 17, 11, 77 is 1.

Therefore, GCD of numbers 34, 17, 11, 77 is 1

Given Input Data is 34, 17, 11, 77

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

Prime Factorization of 34 is 2 x 17

Prime Factorization of 17 is 17

Prime Factorization of 11 is 11

Prime Factorization of 77 is 7 x 11

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(34, 17) = 34

GCD(34, 17) = ( 34 x 17 ) / 34

GCD(34, 17) = 578 / 34

GCD(34, 17) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 11

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

LCM(17, 11) = 187

GCD(17, 11) = ( 17 x 11 ) / 187

GCD(17, 11) = 187 / 187

GCD(17, 11) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 77

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

LCM(1, 77) = 77

GCD(1, 77) = ( 1 x 77 ) / 77

GCD(1, 77) = 77 / 77

GCD(1, 77) = 1

GCD of 34, 17, 11, 77 is 1
