Given Input Data is 520, 819, 551, 574

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

Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13

Prime Factorization of 819 is 3 x 3 x 7 x 13

Prime Factorization of 551 is 19 x 29

Prime Factorization of 574 is 2 x 7 x 41

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(520, 819) = 32760

GCD(520, 819) = ( 520 x 819 ) / 32760

GCD(520, 819) = 425880 / 32760

GCD(520, 819) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 551

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

LCM(13, 551) = 7163

GCD(13, 551) = ( 13 x 551 ) / 7163

GCD(13, 551) = 7163 / 7163

GCD(13, 551) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 574

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

LCM(1, 574) = 574

GCD(1, 574) = ( 1 x 574 ) / 574

GCD(1, 574) = 574 / 574

GCD(1, 574) = 1

GCD of 520, 819, 551, 574 is 1
