Given Input Data is 771, 891, 175, 392

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

Prime Factorization of 771 is 3 x 257

Prime Factorization of 891 is 3 x 3 x 3 x 3 x 11

Prime Factorization of 175 is 5 x 5 x 7

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(771, 891) = 228987

GCD(771, 891) = ( 771 x 891 ) / 228987

GCD(771, 891) = 686961 / 228987

GCD(771, 891) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 175

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

LCM(3, 175) = 525

GCD(3, 175) = ( 3 x 175 ) / 525

GCD(3, 175) = 525 / 525

GCD(3, 175) = 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 771, 891, 175, 392 is 1
