We found the divisors of 19, 77, 11 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 19, 77, 11 is 1.

Therefore, GCD of numbers 19, 77, 11 is 1

Given Input Data is 19, 77, 11

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

Prime Factorization of 19 is 19

Prime Factorization of 77 is 7 x 11

Prime Factorization of 11 is 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(19, 77) = 1463

GCD(19, 77) = ( 19 x 77 ) / 1463

GCD(19, 77) = 1463 / 1463

GCD(19, 77) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 11

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

LCM(1, 11) = 11

GCD(1, 11) = ( 1 x 11 ) / 11

GCD(1, 11) = 11 / 11

GCD(1, 11) = 1

GCD of 19, 77, 11 is 1
