Therefore, GCD of numbers 611, 778, 79, 392 is 1

Given Input Data is 611, 778, 79, 392

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

Prime Factorization of 611 is 13 x 47

Prime Factorization of 778 is 2 x 389

Prime Factorization of 79 is 79

Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7

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(611, 778) = 475358

GCD(611, 778) = ( 611 x 778 ) / 475358

GCD(611, 778) = 475358 / 475358

GCD(611, 778) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 79

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

LCM(1, 79) = 79

GCD(1, 79) = ( 1 x 79 ) / 79

GCD(1, 79) = 79 / 79

GCD(1, 79) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 392

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

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

GCD(1, 392) = 392 / 392

GCD(1, 392) = 1

GCD of 611, 778, 79, 392 is 1
