Given Input Data is 423, 885, 693, 551

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

Prime Factorization of 423 is 3 x 3 x 47

Prime Factorization of 885 is 3 x 5 x 59

Prime Factorization of 693 is 3 x 3 x 7 x 11

Prime Factorization of 551 is 19 x 29

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(423, 885) = 124785

GCD(423, 885) = ( 423 x 885 ) / 124785

GCD(423, 885) = 374355 / 124785

GCD(423, 885) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 693

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

LCM(3, 693) = 693

GCD(3, 693) = ( 3 x 693 ) / 693

GCD(3, 693) = 2079 / 693

GCD(3, 693) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 551

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

LCM(3, 551) = 1653

GCD(3, 551) = ( 3 x 551 ) / 1653

GCD(3, 551) = 1653 / 1653

GCD(3, 551) = 1

GCD of 423, 885, 693, 551 is 1
