Given Input Data is 380, 551, 104, 549

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

Prime Factorization of 380 is 2 x 2 x 5 x 19

Prime Factorization of 551 is 19 x 29

Prime Factorization of 104 is 2 x 2 x 2 x 13

Prime Factorization of 549 is 3 x 3 x 61

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(380, 551) = 11020

GCD(380, 551) = ( 380 x 551 ) / 11020

GCD(380, 551) = 209380 / 11020

GCD(380, 551) = 19

Step2:

Here we consider the GCD from the above i.e. 19 as first number and the next as 104

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

LCM(19, 104) = 1976

GCD(19, 104) = ( 19 x 104 ) / 1976

GCD(19, 104) = 1976 / 1976

GCD(19, 104) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 549

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

LCM(1, 549) = 549

GCD(1, 549) = ( 1 x 549 ) / 549

GCD(1, 549) = 549 / 549

GCD(1, 549) = 1

GCD of 380, 551, 104, 549 is 1
