Given Input Data is 771, 561, 792, 262

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

Prime Factorization of 771 is 3 x 257

Prime Factorization of 561 is 3 x 11 x 17

Prime Factorization of 792 is 2 x 2 x 2 x 3 x 3 x 11

Prime Factorization of 262 is 2 x 131

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(771, 561) = 144177

GCD(771, 561) = ( 771 x 561 ) / 144177

GCD(771, 561) = 432531 / 144177

GCD(771, 561) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 792

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

LCM(3, 792) = 792

GCD(3, 792) = ( 3 x 792 ) / 792

GCD(3, 792) = 2376 / 792

GCD(3, 792) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 262

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

LCM(3, 262) = 786

GCD(3, 262) = ( 3 x 262 ) / 786

GCD(3, 262) = 786 / 786

GCD(3, 262) = 1

GCD of 771, 561, 792, 262 is 1
