Therefore, GCD of numbers 530, 819, 911, 917 is 1

Given Input Data is 530, 819, 911, 917

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

Prime Factorization of 530 is 2 x 5 x 53

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

Prime Factorization of 911 is 911

Prime Factorization of 917 is 7 x 131

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(530, 819) = 434070

GCD(530, 819) = ( 530 x 819 ) / 434070

GCD(530, 819) = 434070 / 434070

GCD(530, 819) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 911

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

LCM(1, 911) = 911

GCD(1, 911) = ( 1 x 911 ) / 911

GCD(1, 911) = 911 / 911

GCD(1, 911) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 917

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

LCM(1, 917) = 917

GCD(1, 917) = ( 1 x 917 ) / 917

GCD(1, 917) = 917 / 917

GCD(1, 917) = 1

GCD of 530, 819, 911, 917 is 1
