Therefore, GCD of numbers 935, 663, 47, 561 is 1

Given Input Data is 935, 663, 47, 561

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

Prime Factorization of 935 is 5 x 11 x 17

Prime Factorization of 663 is 3 x 13 x 17

Prime Factorization of 47 is 47

Prime Factorization of 561 is 3 x 11 x 17

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(935, 663) = 36465

GCD(935, 663) = ( 935 x 663 ) / 36465

GCD(935, 663) = 619905 / 36465

GCD(935, 663) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 47

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

LCM(17, 47) = 799

GCD(17, 47) = ( 17 x 47 ) / 799

GCD(17, 47) = 799 / 799

GCD(17, 47) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 561

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

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

GCD(1, 561) = 561 / 561

GCD(1, 561) = 1

GCD of 935, 663, 47, 561 is 1
