Therefore, GCD of numbers 615, 774, 81, 523 is 1

Given Input Data is 615, 774, 81, 523

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

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 774 is 2 x 3 x 3 x 43

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 523 is 523

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(615, 774) = 158670

GCD(615, 774) = ( 615 x 774 ) / 158670

GCD(615, 774) = 476010 / 158670

GCD(615, 774) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 81

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

LCM(3, 81) = 81

GCD(3, 81) = ( 3 x 81 ) / 81

GCD(3, 81) = 243 / 81

GCD(3, 81) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 523

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

LCM(3, 523) = 1569

GCD(3, 523) = ( 3 x 523 ) / 1569

GCD(3, 523) = 1569 / 1569

GCD(3, 523) = 1

GCD of 615, 774, 81, 523 is 1
