Given Input Data is 561, 671, 741, 891

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

Prime Factorization of 561 is 3 x 11 x 17

Prime Factorization of 671 is 11 x 61

Prime Factorization of 741 is 3 x 13 x 19

Prime Factorization of 891 is 3 x 3 x 3 x 3 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(561, 671) = 34221

GCD(561, 671) = ( 561 x 671 ) / 34221

GCD(561, 671) = 376431 / 34221

GCD(561, 671) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 741

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

LCM(11, 741) = 8151

GCD(11, 741) = ( 11 x 741 ) / 8151

GCD(11, 741) = 8151 / 8151

GCD(11, 741) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 891

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

LCM(1, 891) = 891

GCD(1, 891) = ( 1 x 891 ) / 891

GCD(1, 891) = 891 / 891

GCD(1, 891) = 1

GCD of 561, 671, 741, 891 is 1
